摘要
通过对滑移摩擦支座摩擦力双向耦合性能的模拟,采用基础隔震结构动力分析程序DABIS对基础滑移隔震结构进行了单向和双向地震反应对比分析,分析表明在双向地震作用下结构各层的加速度反应较小,隔震层的层间位移较大,而上部结构的层间位移较小,并且在双向地震作用下,支座的最大位移明显大于单向地震作用时的支座最大位移,因而在确定支座最大位移时应考虑双向地震作用的影响。
The bilateral coupled friction force of sliding-friction bearings is simulated and the comparing analysis on unilateral and bilateral seismic response of sliding base-isolated structure is carried out by the program of dynamic analysis on base-isolated structures (DABIS). It is found that under the bilateral ground inputs the acceleration response of each floor is smaller, the inter-floor displacements of super-structure are smaller, and the maximum displacement of the bearings under bilateral components is much lager than that under unilateral component, so that the influence of bilateral inputs should be considered as to ascertain the maximum displacement of the bearings.
