Abstract
In this research paper consists “seismic analysis of asymmetric reinforced concrete structure with lead rubber bearing”.The configuration of buildings are G+4 and G+9 with storey height is 3m taken.In this work ,the proposed building frame structure with various input parameter such as 5 and 10 multi-storey frame,size of columns are 350X350mm and 400X400mm respectively,size of beams are 300X350mm in both the cases,.thickness of slab is 150mm. Live load is 4 KN/m2,Grade of reinforcement used Fe415, Both the cases are considered to be located in seismic zone III IS 1893 (Part-I):2002. Seismic zone factor, Z=0.3(UBC 97, Vol-2, Table 16-I & Zone Map), Seismic coefficient, C_V = C_VD=0.54(UBC 97, Vol-2, Table 16-R), Response Reduction Factor, R forSMRF=8.5(UBC 97, Vol-2, Table 16-N), Damping coefficient, B_d or B_m=1 Interpolate (UBC 97, Vol-2, Table A-16-C) ,etc are taken.average drift for 5 storey structure reduces to almost 53% while in case of 10 storey structure it reduces to 26% only w.r.t. fixed base structure. average percentage reduction in storey shear of LRB building w.r.t. fixed base building is 48.765% and 70.37% in 5 and 10 storey building respectively.
