摘　　要：以某框架结构为例,建议了并联隔震体系隔震层的初步设计方法,即橡胶隔震支座宜设置在受力较大的位置,对应长期设计荷载小的柱位宜布置摩擦滑移隔震支座.给出了确定柱下隔震支座数量的方法,用SAP2000验证了初步隔震方案的合理性和隔震效果的有效性,可为此类隔震体系的推广使用提供设计参考.Taking the case of a frame structure, We propose a preliminary design method of isolation layer of parallel base isolated system. Namely the rubber isolation bearing should be set up in a larger force position, sliding isolation bearings should be set up in the column position of small long-term design load. Determining method of the isolation bearings quantity under the column is given. The rationality of the initial isolation plan and the validity of isolation effect are verified by using SAP2000 program. It can provide the design reference for the popularization and use of such isolation systems.
