对钢管混凝土边框钢板剪力墙试件和钢管混凝土边框内藏钢板剪力墙试件进行了模拟地震振动台试验,试件高宽比均为3.2。在试验的基础上,利用ABAQUS软件和SAP2000软件分别建立实体模型和宏观模型,对试件进行了弹塑性时程分析,对比了计算结果和实测结果,研究了不同钢板宽厚比和钢管壁厚对试件抗震性能的影响。研究结果表明:钢管混凝土边框内藏钢板剪力墙试件的延性较好,抗震耗能能力较强,可在高层建筑中设计使用;而在两种试件当中,钢管混凝土边框和钢板(内藏钢板)起到的耗能作用均比较突出。
Simulated seismic shaking table tests were carried out on specimens of steel plate concrete wall shear wall and steel tube concrete frame containing steel plate shear wall. The aspect ratio of specimens was 3.2. On the basis of the experiment, the solid model and the macroscopic model were established respectively by ABAQUS software and SAP2000 software. The elasto-plastic time-history analysis of the specimen was carried out. The calculated results and the measured results were compared. The effects of different thickness ratio and wall thickness Impact of specimen on seismic performance. The results show that the specimens with steel plate shear wall built in the concrete filled steel tubular frame have better ductility, stronger seismic energy dissipation capacity and can be designed and used in high-rise buildings. Among the two specimens, the CFST frame and steel plate Cangban) play the role of energy consumption are more prominent.
