A Comparative Study of the Seismic Behaviour of G+20 Storey Symmetrical Buildings Constructed with Light Weight Concrete and Normal Weight Concrete

Abstract

Abstract: Concrete with a density of less than 2000 kg/m^3 is considered lightweight concrete. Structural lightweight concrete (SLWC) is used to reduce the dead load of concrete structures. The purpose of this research is to examine and compare the results of SLWC made with scoria and normal weight concrete (NWC) and normal and light weight concrete(NAL) multistorey buildings. Multistorey buildings are often constructed of ordinary concrete, steel, and other materials. They are subjected to heavy loads, requiring heavy construction that may not be cost-effective. In this paper, a G+20multistorey plan symmetrical building is analysed using the response spectrum method with SLWC and NWC. Bending moment, shear force, storey shear, storey drift, and storey displacement are considered. The results of the NWC and SLWC and NAL buildings are compared . Concluding the research work that when comparing symmetrical plan area cases of normal concrete, light weight concrete and combination of normal and light weight concrete for all the result parameters, light weight concrete seems to be very efficient and most favorable case. Hence should be recommended when this type of construction procedure will be adopted, i.e. always use building with lightweight concrete
