Another advantage of steel structures is that they can be constructed off-site by professional steel fabricators and then assembled on site. Figure (2.2): Basic shapes of lightweight concrete. stabilize the building as a whole by acting as a diaphragm to transfer wind loads to the walls and columns, temporary construction load usually governs the choice of decking profile, It is assumed to Resist a small axial load. Composite Columns. The bending stiffness of steel columns of H-or I-section is much greater in the plane of the web (‘major-axis bending’) than in a plane parallel to the flanges (‘minor-axis bending’). Disadvantages of Steel Structures 01. Here we are going to focus on the advantages and disadvantages of structural steel structures. It has a high strength to weight ratio which means it has high strength per unit mass. Read Introduction on Composite Structures Here. Disadvantages: Brittle failure Curing plays important role in gaining strength (which is neglected many a times) Steel is required for taking complete advantage of concrete Zero (or little) scrap value 1 INTRODUCTION. Increased strength for a given cross sectional dimension. The system chosen depended on a variety of factors including land/site constraints, design functionality and … Super flat Ff numbers are possible. framed structure. The main benefit of composite elements is that the properties of each material can be combined to form a single unit that performs better overall than its separate constituent parts. While local buckling of the steel sections may be eliminated, the reduction in the compression resistance of the composite column due to overall buckling should definitely be allowed for. Steel concrete composite beams consists of a steel beam over which a reinforced concrete slab is cast with shear connectors. An example in civil structures is the steel-concrete composite beam in which a steel wide flange shape is attached to a concrete floor slab. By combining these two materials in the right way, it is possible to design a composite of mechanical properties and functional characteristics.

There are two main benefits of composite action in structural members. This results in much reduced maintenance and repair costs. The reasons for this reliability include consistency and uniformity in properties, better quality control because of factory manufacture, large elasticity, and ductility. Easy Installation of services The interface is a bounding surface or zone where a discontinuity occurs, whether physical, mechanical, chemical etc. Masonry is extremely solid and can last a long time. Application of Carbon Fiber Reinforced Polymer in Concrete Structures Carbon fiber reinforced bars . Reduction of height reduces the total of the building –> saving area of cladding, Longer spans with the same height  –> column free rooms, Additional storeys with the same total height of building, Saving costs, earlier completion of the building, Ready for use earlier thus increasing rental income, Modification during the life of the building, Modify services without violating the privacy of other occupants, Reinforcement of profiled steel sheetings, Quality controlled products ensure greater accuracy, Capital expenditure about 145 million Euro. Steel structures are very reliable. This concrete is known as no fines concrete (Neville and Brooks, 2010; Slaby, Aziz and Hadeed, 2008). STRUCTURAL STEEL AND COMPOSITE SLAB ON DECK STRUCTURE ... POST-TENSIONED CONCRETE STRUCTURE. A steel-concrete composite column is a compression member, comprising either a concrete encased hot-rolled steel section or a concrete filled tubular section of hot-rolled steel. The concrete plays a very important role in all branches of civil engineering. Such arrangements seek to combine their different properties to … Lightweight aggregates are used to produce lightweight concrete when the weight of aggregates is lower than 1120 kg/m3 (Mehta and Monteiro, 2006). Applications such as underground cabling and others that require more strength may use the medium or heavy duty PVCs depending on the amount of pressure they exert on the conduits. The concrete and steel is utilized effectively. Corrosion protection in encased beams. Concrete when used along with reinforcement, is capable of taking bending and tension forces. Thanks for sharing the advantages and disadvantages of these structures. The many other kinds of composite beam include steel-wood, wood-concrete and plastic-concrete or advanced composite materials-concrete. In Composite columns steel and concrete will counterattack external load by joining with each other by bond or in between their friction. Reliability. Lighter construction than a traditional concrete building. To obtain desirable properties in a composite, the applied load should be effectively transferred from the matrix to the fibers via the interface. 3 thoughts on “Steel Structure Vs RCC (Concrete) Structure Buildings -Pros, Cons & Application” Arjoon. Steel is a highly durable metal. Well “wetted” fibers increase the interface surfaces area. These two components act independently under the action of loads, because there are no connection between the concrete slabs […] Coupling agents are frequently used to improve wettability. Low post cracking capacity. At lower stress levels, concrete is relatively constant but it starts to decrease at higher stress levels.The coefficient of thermal expansion of concrete is very low and all concrete structures will fail to some extent, due to shrinkage and tension.Hence, we, Both thermosetting plastic as well as thermoplastic have high thermal as well as corrosion resistance but thermoplastic shows self-lubricating property because of its linear structure. More economical steel section is used in composite construction than conventional non-composite construction for the same span and loading. Connecting the concrete to the steel beams can have several advantages: • It is typical to have a reducedIt is typical to have a reduced Shallower beams may be used structural steel frame cost • Weight of the structural steel frame may be decreased which • Shallower beams may be used which might reduce building height • Increased span lengths are possible nowadays, the main focus has been shifted to constructing safe buildings keeping in mind the economic aspects of the project, As … High Maintenance & Capital Cost.

The performance of a composite material system depends mainly on the interfacial properties of the reinforcement and the matrix material . Steel can be considered a homogeneous material and its ft and ductility are very high. Traditionally two counteracting methods of construction could be observed both connected with special advantages but also disadvantages worth mentioning. Along with many advantages, reinforced concrete also poses some disadvantages also. Some thermosetting plastic with high thermal resistance that can be used, Advantage And Disadvantage Of Composite Construction, For finding specific gravity of cement kerosene is used. Steel & Composite Structures, An International Journal, provides and excellent publication channel which reports the up-to-date research developments in the steel structures and steel-concrete composite structures, and FRP plated structures from the international steel community. Few properties wherein solid structures are preferred over steel and the utilization of steel is consistently expanding everywhere throughout the world in development projects. Significant economic advantages over either pure structural steel or reinforced concrete alternatives. This means you get to save money in waste management. Resistance to a wide range of chemical agents including acid rain and salt spray, conditions under which metal parts would suffer. High-rise buildings b. Composite structures help reduce the sizes of steel beams (thereby allowing for more headroom) and also provide increased structural stability. Composite slabs using steel decking are considerable stiffer and stronger than many other flooring systems, so the weight and size of the primary structure can be reduced. The many other kinds of composite beam include steel-wood, wood-concrete and plastic-concrete or advanced composite materials-concrete. Some of the common disadvantages of using steel buildings are High Maintenance & Capital Cost, Susceptibility to Buckling, Fatigue and Fracture, Fireproof Treatment, Fire Damage and Fabrication Error. 1. Resistance/Weight ratio; greater resistance with lese weight, thus enabling a global reduction of the structure’s weight.The minimum slab edge measures a mere 12 cm. wider. This is because of their unique properties such as mechanical, thermal, and electrical properties. Concrete assumes the shape of its mould and it can be poured and cast into any shape. The ductility performance of circular type of columns is significantly better than rectangular types. The plastic compression resistance of a composite cross-section represents the maximum load that can be applied to a short composite column. Following are a list of advantages of steel structure construction offers: 1. Knee bracing could be employed to provide the desired ductility level for a ductile design. Unlike natural stones, concrete is free from defects and flaws. Reinforced concrete, as an economic building material, is very popular nowadays. Advantages of Composite Construction The concrete acts together with the steel to create a stiffer, lighter, less expensive structure. There is no requirement to provide additional reinforcing steel for composite concrete filled tubular sections. Pushover tests were conducted on scaled models of ductile unit frames, directly braced by X and Knee steel braces. The presence of micro cracks in the concrete play a significant role in decreasing the strength of plain concrete, this problem can be solved by adding different fibers in the mixture of the concrete, many kinds of concrete can be used one of them is steel fibers which we. Composite bridges are more and more popular around the world since they combine some advantages of steel bridges with some key factors of concrete bridges. Concrete can be manufactured to the desired strength with an economy. Speed and simplicity of construction- faster to erect, nearly 25% faster then traditional construction. Consist of profiled steel decking with an in-situ reinforced concrete topping. Brittleness and low ductility. Besides that, concrete is a material which can be formulated with high compressive strength but significantly low tensile strength. Advantages of composite beams: The concrete and steel is utilized effectively. Only by combining several materials can one meet the performance requirements. Composite construction is widely recognised nowadays as an efficient way of enhancing the structural performance of steelwork by ensuring that, when used in association with concrete, the two materials act as a unit. Introduction Monolithic metals and their alloys cannot always meet the demands of today’s advanced technologies. As stated, the main advantage of fiber-reinforced concrete is the reduction of shrinkage and cracking. The profiled steel formwork that supports the concrete floor during casting is of vital importance as it also provides the shear bond to enable the materials to work compositely. The worked example, a multi-storey framed structure for a building, includes design to draft Eurocode 4: Part 1.2 for resistance to fire. The lightest wall is suitable for embedding in the walls or above the ceilings during construction or upgrades. The evaluation of mechanics of RC members made of two materials is very difficult because one of the materials, which is Conc., behaves differently in tension than in compression and may be considered to be inelastic. Pros and Cons of Three Concrete Structure Methods Over the years, we’ve built parking structures that employed different structural framing methods. All deck work is formed in place, requiring large resources of forming materials, shoring scaffolds and labor. All the Advantages & Disadvantages Of Steel Structures are explained in order to know complete information about steel. Thanks for the comparison. In conventional composite construction, concrete slabs are simply rested over steel beams and supported by them. 2. 3. Advantages of Composite Construction. It is fully consistent with the latest codes for the design of concrete and steel structures, Eurocode 2 and 3 respectively. 1- The tensile strength of reinforced concrete is about one-tenth of its compressive strength. Steel is tensile. Structural members that are made up of two or more different materials are known as composite elements. The main benefits of composite slabs are as follows: Versatility; they can be adapted to many practical cases and a multitude of solutions. Consequently, foundation sizes can also be reduced. Paul Sekatawa. (Newman and Choo, 2003) There are two main benefits of composite action in structural members. Read Introduction on Composite Structures Here. Composite Slabs & Columns – Advantages and Basic Concepts. This makes the installation and fitting of the PVC non-metallic conduit very easy, quick and less expensive since it requires fewer couplers and bends. Figure (2.2) shows these types of lightweight concrete. The concrete acts together with the steel to create a stiffer, lighter, less expensive structure. If a masonry structure uses lime mortar, the useful life can last more than 500 years, compared to 30 to 100 years when using steel or reinforced concrete (depending on exposure and treatments). Advantages of Steel Construction 1. Susceptibility to Buckling. The material is also weather resistant; the exterior walls can hold up heavy storms and high temperatures. Unlike natural stones, concrete is free from defects and flaws. The advantages of using composites include: 1. Disadvantages of Reinforced Concrete. An example in civil structures is the steel-concrete composite beam in which a steel wide flange shape is attached to a concrete floor slab. The concrete plays a very important role in all branches of civil engineering. The location and count of post tension cable is a must. The decking(profiled steel sheeting) not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely, span between 3 m and 4.5 m onto supporting beams or walls. High strength/weight ratio. Now a Days, because of large constructions and high-storey buildings of 10 and above, the size of columns increases because of the revised IS – codes and FSI. The reliability and safety of the concrete structures are specified depending on their function and the place of their achievement. advantages and disadvantages of them in concrete structures are investigated. the matrix material must “wet” the fiber. Composite floor decks are comprised of either steel beams or concrete embedded steel beams together with a reinforced concrete slab. Less material handling at site. Advantages of Structural Steel Structures. And the second one is steel whose properties define well. Steel structures are an eco-friendly option as they are easily recyclable. 9. Ingredients of concrete are easily available in most of the places. 2.1.3.2.1.1 Lightweight aggregate concrete: ADVANTAGES AND DISADVANTAGES OF STEEL AS A STRUCTURAL DESIGN MATERIAL The following advantages in general may be credited to steel as a structural design material: 1. The right fiber-reinforced concrete can also provide impact-resistance, increase tensile strength and reduce voids in the concrete. Steel and composite structure gives more ductility to the structure as compared to the R.C.C. It is usually available in three main wall thickness or gauges. In addition, carbon nanotubes have high aspect ratios and more surface area per gram which make them suitable for their use as multi-functional reinforcement materials in polymer matrixes , . It can withstand a considerable amount of external pressure. Concrete can be manufactured to the desired strength with an economy. If the slab is propped, all of the loads have to be resisted by the composite section. Good fire resistance in the case of concrete encased beams. Advantages and Disadvantages of Fiber-Reinforced Concrete. All the design methods explained in this volume are those of the Eurocode. Carbon fiber reinforced polymer bars are currently used to reinforce concrete in an attempt to overcome the corrosion issue encountered with ordinary steel. Nethercot, in Stability and Ductility of Steel Structures (SDSS'97), 1998. Conc.. is, non-homogenous making from different materials. If the slab is unpropped during construction, the decking alone resists the selfweight of the wet concrete and construction loads. Very nicely written blog. Lighter construction than a traditional concrete building. PVC conduit is the most common type for residential and commercial installations. Carbon nanotubes (CNTs) have widely been used as reinforcement in polymer matrix–based composites. Fiber reinforcement concrete is a composite material consisting of cement paste, mortar, or concrete with fibers of asbestos, glass, plastic, carbon or steel. Keywords: chromite, Styrofoam, ... ceilings such as Composite steel concrete precast beams with chromite and beam with Styrofoam, and each with advantages and disadvantages, thorough this article they'll be mentioned and related discussions will be presented. The compressive strength of concrete is very high making it … are usually designed as simply supported members in the normal condition, yield strengths ranging from 235 N/mm2 to at least 460 N/mm2, The various shapes provide Interlock between steel and concrete. Ingredients of concrete are easily available in most of the places. Resilience – the ability to deform and spring back to their original shape without major damage. It is because these ingredients may accelerate or slow down the rate of concrete hardening and affect the tensile strength entrainment of air and water resistance of concrete.Typically, we mix about 10% to 15% of cement, 60% to 75% of aggregate and 15% to 20% of water to produce concrete. The use of advanced composite materials such as GFRP fiberglass rebar can help resolve typical deterioration problems that are associated with conventional steel reinforcement materials. and steel, both of which have entirely different mechanical properties. Time must be spent waiting for concrete … Test outcomes indicate that the yield capacity and the strength capacity of a ductile RC frame could be increased and its global displacements could be decreased to the desired levels by directly adding either an X bracing or a knee-bracing system to the frame. Steel structure construction has numerous advantages over concrete construction. The durability of concrete is very high. to reduce the effective slenderness of the steel member, which increases its    resistance to axial load. Concrete resists compression and steel reinforcement resists tension forces. The durability of concrete is very high. Subsequent loads are applied to the composite section. Speed and simplicity of construction- faster to erect, nearly 25% faster then traditional construction. Composite floor decks are comprised of either steel beams or concrete embedded steel beams together with a reinforced concrete slab. So no matter how large the overall structure is, the steel sections will be small and lightweight, unlike other building materials. While rubbing of wheels on the rails develops shear stress that causes linear structured molecules to slide over each other and act as lubricating property and reduces friction effect and greatly reducing efficiency of friction brakes. Composite slabs Consist of profiled steel decking with an in-situ reinforced concrete topping. Thermosetting plastics do not have self-lubricating property and have high thermal resistance of around 200C to 300C which are suitable for this purpose. 1.1.1. which is best suited under the effect of lateral forces. In concrete mixes,entrained air may take up another 5% to 8%. Advantages of Concrete. This property makes steel a very attractive structural material for a. The profiled steel formwork that supports the concrete floor during casting is of vital importance as it also provides the shear bond to enable the materials to work compositely.
