Abstract
- In civil engineering when there is a talk of strength of the structure, the major problem which affects the strength of the structure is earthquake. Many researches and experiments have been done in the field of earthquake or seismic resistant design of the structure. Base isolation technique is one in the row in designing earthquake resistant structures. Isolation at the base of the building or isolation at any storey or mid storey can be done while design the structure. This technique found to be very helpful in this field. In this paper, base isolation as well as inter-storey isolation technique has been used in irregular building for designing the seismic resistant building. Mass irregularity has been taken into consideration. G+10, G+20 and G+30 irregular structures have been used and all analysis is done on ETABS software. Different parameters like story drifts and stiffness are taken for comparisons
