Abstract:

Concrete is the most important material used in many construction applications. The multistorey buildings are constructed of ordinary concrete, steel and other materials and are subjected to heavy loads requiring heavy construction and may not be cost effective. But the structural lightweight concrete produced using lightweight aggregates may reduce the dead load of the structure, so now a days it is used in construction of multistorey buildings. Concrete is considered as light weight concrete which has density of less than 2000 kg/m3. In this research, a G+10 multistorey plan irregular building is analysed with structural lightweight concrete using perlite as a fine aggregate and normal weight concrete using the Response Spectrum Method under different seismic zones and Time History Method for Bhuj earthquake. The parameters like storey displacement, storey drift, storey shear and overturning moments are considered and the results of NWC and SLWC buildings are compared. From the results obtained it is observed that seismic damages are considerably reduced in structural lightweight concrete buildings as compared to normal weight concrete buildings.
