摘要近年来，在日本发生的地震中，由于非结构性钢筋混凝土墙的破坏，一些钢筋混凝土建筑物在地震后很难保持其功能。目前，社会期望建筑物在地震后迅速恢复，如果不是不间断的功能。根据2015 AIJ规范，对4个混合摇摆墙试件、沿着摇摆墙试件和RC墙试件进行了试验，以量化其破坏水平和极限状态。采用多弹簧模型对混合摇摆墙的性能进行了模拟。结果表明，对分析墙体的极限状态进行了成功的分类，与实验结果吻合良好。
ABSTRACT In recent earthquakes in Japan, it was difficult for some reinforced concrete buildings to maintain their functionality after earthquakes due to damage to nonstructural RC walls. Currently, society expects quick recovery, if not uninterrupted functionality, of buildings after earthquakes. In this paper, four hybrid rocking wall specimens, along with rocking wall and RC wall were tested to quantify the damage level and limit states based on the 2015 AIJ guidelines. The behaviour of hybrid rocking walls was modelled with amulti-spring model. As aresult, limit states of analyzed walls were successfully classified in agood agreement with experimental results.
