Reinforced concrete began to be introduced as a common material in frame construction since 1960. ; Expensive formwork is required for casting and molding and to hold the concrete in place until it hardens sufficiently. Frame structures can be constructed rapidly. Hence, a framed structure is a structure having the combination of beam, column and slab to resist the gravity and other lateral loads. Disadvantages – Span lengths are usually restricted to 40ft when normal reinforced concrete otherwise spans greater than that , can cause lateral deflections. Cast-in-place concrete is a common type of building material for commercial structures and residential homes alike. The tensile strength of reinforced concrete is about one-tenth of its Frame structures are the structures having the combination of beam, column and slab to resist the lateral and gravity loads. Public and private developers should also realize that using cast-in-place reinforced concrete to frame a high-rise office building would yield more rentable space because of lower floor-to-floor heights. Fire risks. There are many advantages of precast concrete. Conclusion: 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). An In-Depth Look at Concrete Construction. Advantages of Prestressed concrete Low maintenance cost is enough. The construction activity can be finished in a short period. Though it may also be made using plywood or masonry structure. The cost of a frame system alone should not dictate the choice of frame for a project. 1.One of the best advantages of frame structures is their ease in construction. DISADVANTAGES Concrete being the porous material may lead to the problem of seepage Due to its geometry, it is not possible to add another floor above it. Due to numerous advantages framed structures are constructed all over the world. Frame structures can be constructed rapidly. Advantages of Reinforced Concrete. In commercial applications, concrete is superior to wood framing when the structure must be completed quickly. In addition, structural components can be supplied for incorporation into a structure on-site. Advantages of Frame Structures 1- One of the best advantages of frame structures is their ease in construction. Steel structure, has many advantages over wooden/RCC structure. Reduction in Energy Use Up to 9% of total annual energy costs could be saved through the use of the thermal mass of cast-in-place concrete, according to the Massachusetts Institute of Technology (MIT). Advantages Behaviour. The tensile strength of reinforced concrete is about one-tenth of its compressive strength. Rcc Concrete is considered as a chemically combined mass where the inert material acts as a … ADVANTAGES AND DISADVANTAGES OF REINFORCED CONCRETE Reinforced concrete has some characteristics that enhance its ability to resist earthquake forces, and others that are detrimental. Expensive formwork is required for casting and molding and to hold the concrete in place until it … Moment Resisting Frame (steel) used as a shear wall. Due to the frame, the reinforced concrete can also withstand a good amount of tensile stresses. The concrete structure is a highly rigid frame, which reduces vibration and bounces when compared with steel structure. A well-built steel structure can last up to 30 years if maintained well. The precast concrete … Your email address will not be published. Disadvantages of Reinforced Concrete 1.
