摘要: Abstract In long base isolated buildings the superstructure may consist of several parts separated by narrow thermal expansion joints. such cases, neighboring bearings which support adjacent are connected together at their top so that they form a common isolation and prevent impact level. The analysis constitutes problem multiple base-isolated structure with basemat system. This situation can not be analyzed existing algorithms capable analyzing only single structure. torsional characteristics combined system different than those individual on systems. Hence, needs to in its entirety rather each building separately. this paper an analytical model algorithm analyze presented. Verification accuracy comparison results obtained using general purpose finite element program A is used demonstrate importance as against buildings.
