对钢管混凝土组合异形柱构体系进行了抗震性能分析,分别建立6组模型来分析框架梁与混凝土剪力墙连接方式不同、楼板厚度不同以及外侧钢管混凝土组合柱截面形式不同对结构抗震性能的影响。分别对结构进行了模态分析和反应谱分析,比较不同变量对结构动力响应的影响以及对结构层位移、层间位移角、层间剪力和层刚度的影响。
The seismic performance of CFST special-shaped column system was analyzed. Six models were set up to analyze the influence of different connection modes of frame beam and concrete shear wall, different thickness of slab and different cross-section of CFST column on the seismic behavior of the structure. . The modal analysis and response spectrum analysis of the structure were carried out respectively. The influence of different variables on the dynamic response of the structure and the influence on the displacement of the structural layer, the displacement angle of the interlayer, the interlaminar shear force and the stiffness of the layer were compared.
