【摘要】：为研究型钢混凝土十字形异形柱的抗震性能,完成4个不同轴压比、配钢率、加载方向试件的低周反复荷载试验。对不同设计参数试件的破坏形态、滞回性能、骨架曲线、变形能力、耗能能力进行分析。根据试验结果,采用ABAQUS对试件进行有限元分析,分析得到的试件的破坏形态、骨架曲线及承载力与试验结果总体上吻合较好。试验及有限元分析结果表明:型钢混凝土十字形异形柱具有良好的延性、塑性变形能力和耗能能力。与钢筋混凝土十字形异形柱相比,型钢混凝土十字形异形柱承载力高、抗震性能好,可适用于高层建筑以及抗震设防烈度较高地区的建筑中。
[Abstract]:In order to study the seismic behavior of cross shaped steel reinforced concrete columns, the low cycle cyclic loading tests of four specimens with different axial compression ratio, steel distribution ratio and loading direction were carried out. The failure mode, hysteretic property, skeleton curve, deformation ability and energy dissipation ability of the specimens with different design parameters were analyzed. According to the test results, the finite element analysis of the specimen was carried out by ABAQUS, and the failure pattern, skeleton curve and bearing capacity of the specimen obtained from the analysis were in good agreement with the test results on the whole. The results of test and finite element analysis show that the cross shaped steel reinforced concrete column has good ductility, plastic deformation capacity and energy dissipation capacity. Compared with reinforced concrete cross shaped columns, steel reinforced concrete cross shaped columns have high bearing capacity and good seismic performance, and can be used in high-rise buildings and buildings with high seismic fortification intensity.
