摘要
对一榀钢框架与一榀加草土填充墙钢框架进行了ABAQUS有限元分析,得到了该体系在低周反复荷载作用下的变形及应力分布状况,并和纯钢框架从承载能力、滞回性能、延性、耗能能力等方面进行对比分析。结果表明加草土填充墙钢框架具有更高的抗侧刚度和承载能力,在墙体开裂前的延性和耗能能力均优于纯框架,是一种较好的抗侧力体系。
Finite element analysis for a steel frame and a steel frame with grass-soil wall infill which are carried out in this paper by using the software ABAQUS. The deformation and stress distribution of the steel frame with grass-soil wall infill under low cyclic loading are got, which is then compared with the steel frame on beating capacity, hysteretic behavior, ductility and energy dissipation capacity. It is proved that the steel frame with grass-soil wall infill not only has higher lateral stiffness and carrying capacity, but also has better ductility and energy dissipation be- fore the wall cracking, which indicate it＇s a lateral resistant system.
