000010189 520__ $$2eng$$aTo study the effect of torsion in seismic behavior of base isolated structures ,a symmetric four story concrete structure was chosen as the reference model. Then models with eccentricity of 5%,10%,15% and 20% of the dimension of the structure ,are considered. In nonlinear time history analysis, seven records on soil type C according to IBC2003 code normalize to peak ground acceleration equal to 0.4g are used. The isolations are made of rubber and they have modeled with bilinear behavior, in three types. The purpose of this paper is; studying of maximum isolation deformation among the other bases isolations, calculating the range of bases isolation eccentricity to super structure dimensions and decreasing the effect of torsion in base isolated structure, with stiffening the flexible edge.
