摘要
针对屈曲约束支撑,本文根据其反复荷载作用下的滞回特征,提出了一种滞回模型,并建立了屈曲约束支撑的弹塑性刚度方程。根据这种模型编制程序模拟绘制了屈曲约束支撑的滞回曲线,将模拟计算曲线与试验所得曲线进行对比,对比结果表明本文所提模型是准确、有效的。
Based on the hysteretic behavior of buckling-restrained brace under cyclic load, the hysteresis curve mode and stiffness formula of buckling-restrained brace were established. A calculation program for simulating the curve model put forward in this paper is an exact and valid model.
