摘要:
研究以某同高宽比弹塑性隔振建筑结构为工程实例，采用SAP2000软件构建了同高宽比弹塑性隔振建筑结构的有限元模型，并进行了模型材料和相应参数选取；在此基础上，利用循环侧推分析隔振建筑结构中各构件的内力及变形情况，建立隔震建筑结构损失模型，同时为了提高其抗震性评估精准度，采用动力弹塑性顶层位移情况反应隔震建筑结构的抗震性能。工程实例分析结果表明，普通建筑结构主要控制层间位移响应，无论是在8度频发地震作用下还是在8度特大地震作用下，隔震建筑结构的顶部加速度响应均远远小于普通建筑结构，且仍然处于完全弹性工作状态，结构构件并未发生破坏，保证了建筑内部人们的生命财产安全，同时便于震后快速修复，相比于普通建筑结构，同高宽比弹塑性隔振建筑结构的抗震性能更优。
Abstract:
Taking an elastic-plastic vibration isolation structure with the same aspect ratio as an engineering example，the finite element model of the structure with the same aspect ratio is constructed by SAP2000 software，and the material and parameters of the model are selected. On this basis，the internal force and deformation of each component in the structure are analyzed by cyclic lateral pushing，and the loss model of the structure is established. Meanwhile，in order to improve the accuracy of seismic performance evaluation，dynamic elastic-plastic top-story displacement is used to reflect the seismic performance of isolated buildings. The analysis results of engineering examples show that the common building structure mainly controls the inter-story displacement response，the top acceleration response of the isolated building structure is far less than that of the ordinary building structure under 8-degree frequent earthquake or 8-degree extreme earthquake，and it is still in full elastic working state. The structural components are not destroyed，which guarantees the lives of people inside the building. The property is safe and easy to be repaired quickly after earthquake. Compared with the ordinary building structure，the elastic-plastic vibration isolation structure with the same height-width ratio has better seismic performance.
