钢框架内填钢板深梁协同分析

摘要

In order to meet the need of gradient amplitude modulation of the stiffness of steel structure buildings in a certain range, and improve the seismic behavior of the steel structure buildings, the steel deep beam as a new type of lateral force resistance member was proposed. Through horizontal low cyclic loading test, pure steel frame and steel deep beam infilling steel frame were analyzed, and the structures were simplified properly. The viable interactive analysis model of steel deep beam infilling steel frame was obtained by contrasting two simplified models. The study results show that steel deep beam infilling steel frame can significantly improve initial stiffness, yield load and ultimate bearing capacity of pure steel structure.%为了满足钢结构房屋刚度一定范围的渐变调幅需要,提高钢结构房屋的抗震性能,提出了一种新型的抗侧力构件——钢板深梁;通过水平低周反复荷载试验对纯钢框架和钢框架内填钢板深梁进行分析,并对结构进行适当简化;通过对2种简化模型进行对比得出较为可行的钢板深梁与钢框架协同分析模型.研究结果表明:内填钢板深梁可以大幅度提高纯钢结构的初始刚度、屈服荷载和极限承载力.
