摘要
[提要]为了研究高层混合结构的抗震性能,进行了一个30层型钢混凝土框架核心筒结构模型的拟静力试验,结构层2为转换层,模型缩尺比例为1∶10。介绍了模型设计、试验概况和主要试验结果。试验发现:型钢混凝土框架与核心筒的协同作用,使整体结构有较高的承载力,也具有一定的延性,抗震性能较好;结构未发生层剪切破坏,最终破坏模式是在倾覆力矩作用下底部核心筒受拉墙肢及受拉侧外框柱拉断。
In order to study the seismic performance of high-rise steel-concrete hybrid structure, an 1∶10 pseudo-static model test of 30 storied steel reinforced concrete frame-core wall structure with transfer story was done. This paper introduces the design of the model, program of the test and main results. It can be found through the test that the steel reinforced concrete frame can coordinate with the core wall well and provide the whole structure with higher strength, adequate ductility and better seismic performance. The final failure mode of the model is tension failure of perimeter columns and bottom of core wall on the tension side caused by overturning moment, and the story shear failure mode was not found.
