摘要
为进一步了解传统风格建筑钢-混凝土组合框架的抗震性能,在1榀缩尺比为1∶2的传统风格建筑钢-混凝土组合框架拟动力试验的基础上,利用SAP 2000软件建立有限元模型,重点分析结构在地震作用下的受力性能和破坏机制。其有限元模拟的位移时程曲线与试验结果较为吻合,塑性铰出现在结构穿插枋和框架柱处,穿插枋在模拟中率先出铰并最终破坏,故在结构设计中应予以重视。在整个有限元模拟过程中,结构的最大层间位移角达到1/48,同时结构的延性系数为3.14,表明传统风格建筑钢-混凝土组合框架具有良好的抗震性能。
Based on the pseudo-dynamic experiment of a 1 ∶ 2 model of traditional style steel-concrete composite frame,the mechanical properties and the failure mechanism of the frame were investigated by using SAP 2000 to conduct the dynamic elastic-plastic analysis. The finite element calculation displacement results were in a good agreement with the test results,and the plastic hinge occurred at the penetrating tie and the frame column. The first plastic hinge appeared at the penetrating tie and the penetrating tie got failed at first,which indicated that the penetrating tie should be paid more attention for structure design. In the finite element simulation,the maximum inter-story drift angle of the structure reached 1/48,and the ductility coefficient was 3. 14,which indicated that the traditional style steel-concrete composite frame had good seismic performance
