摘要
采用ANSYS软件进行了数值模拟,分别对比了三种型钢截面形式和三种轴压比对型钢高强混凝土柱的延性和耗能性能的影响。从计算结果可以看出,轴压比越小,延性系数越大,抗震性能越好;带翼缘十字形型钢柱的延性比不带翼缘十字形型钢柱的延性好。
By adopting ANSYS numerical simulation methods, the paper compared the effects of three steel cross-section forms and three axial compression ratios on the bearing capacity and ductility of steel of high-strength concrete columns respectively. The results showed that the smaller the axial compression ratio, the greater the ductility factor, and the better the seismic per formance, the ductility of cross-type steel co[umn with flange is better than those without flange.
