填充墙钢框架体系的受力性能分析

Mechanical Behavior of Infilled Steel Frame Structure

通过对填充墙钢框架和同尺寸纯钢框架结构的数值模拟,从两种不同形式的框架结构在单调荷载作用下的荷载——位移曲线、低周反复荷载作用下的滞回曲线、骨架曲线及刚度退化曲线,分析得知填充墙钢框架体系是一种理想的抗侧力体系,其优势表现在该结构的耗能能力、极限承载能力、延性、变形恢复能力及抗侧刚度均优于纯钢框架。

Through numerical simulation of infilled steel frame structure and pure steel frame structure of same size,the paper analyzed two different structures under monotonic loads—displacement curve,hysteresis curve under cyclic loading,skeleton curve,and stiffness degradation curve and obtained that the infilled steel frame structure is an ideal structure with good lateral stiffness.The comparison shows that the infilled steel frame structure in ultimate bearing capacity,deformation resilience aspects,lateral stiffness,ductility and energy dissipation capacity are better than pure steel frame.
