带ALC墙板的钢框架结构滞回性能分析

Hysteretic behavior analysis of Steel frame structure with ALC walls

通过对单跨双层两榀纯钢框架和四榀带ALC墙板钢框架在水平静力及反复动力加载的ANSYS模拟,研究了竖排外挂和竖排内嵌ALC墙板对钢框架结构极限承载力、刚度和滞回性能的影响.发现两种连接方式的ALC墙板和钢框架之间连接性能很好,其中内嵌式ALC墙板对于墙体和框架之间共同工作发挥很大作用.通过有限元分析和试验结果比较,发现有限元分析能较好地模拟试验过程,大部分结果与试验结果吻合较好,并对试验结果进行了适当补充,进而提出了一些有益的结论.

The finite element simulation program ANSYS was used out to study the reaction of 6 steel frames of single span and two stories to horizontal loading and to cyclic loading. 2 frames are pure steel frames and the other 4 with ALC wall panels. The effects of the ALC wall panels out-hung or in-filled on the ultimate strength, stiffness and hysteretic behavior of steel frames were studied. The two modes of connection between ALC panels and steel frames work quite well and the in-filled ALC wall panels can play an important role in the interaction between walls and steel frames. By comparing with experimental data, the finite element analysis works well and most results are in good agreement with test measurements. Based on the ANSYS simulation, some supplementary informations were obtained and some useful conclusions were drawn out.
