本文通过３个轻质填充墙异型柱框架模型在反复水平荷载作用下的试验研究［１］～［３］，分析了结构弹塑性特征、层刚度及其衰减过程，给出了弹性阶段层刚度的计算公式，计算结果与实测值符合较好。 In this paper, through the experimental study [3] of three lightweight filled wall special-shaped column frame models under repeated horizontal loads [1] ~ [3], the elasto-plastic characteristics, layer stiffness and attenuation process of the structure are analyzed, and the elastic stage stiffness is given. The calculation formula is in good agreement with the measured values.
