Comparative Design and Analysis of Composite and RCC Structure

With rapid growth in population along with the development of industrial and commercial activities rapid urbanization has taken place which has resulted into continuous influx of rural people to metro cities in India. So obviously the horizontal space constraint is reaching an alarming situation for metros. To cope with the situation maximum utilization of space vertically calls for the construction of multistoried buildings in large numbers but the question of affordability of the target customers mainly the middle income group of our country necessitates efficient and cost effective design of such buildings. While the concept of cost comparison considering time value of money is popularly advocated and practiced all over the world particularly south east area the same has not been given due to consideration till date India. Uses of reinforced cement concrete as material of construction is well known in India mostly due its lesser direct construction cost with respect to other alternatives. Studies are required to be done for reducing the direct construction cost with alternative options following advanced technologies already prevalent in developed countries. Due to increased in demand and scarcity in supply with respect to the affordable housing projects in India, builders are continuously looking for some alternative technology which may increase their profit margin i.e. return on investment. It has been reported that buildings with purely steel structures are economic only when the overall form of the building is regular and it is possible to use bracings at least along the longer direction without hampering the aesthetics of the building. Therefore it is important to examine the cost competitiveness of the steel concrete composite option which is faster method of construction for structures having irregular shape and variation and height, cladding and floor area. An important and economic combination of construction materials is that of steel and concrete, w
