摘　　要：提出了沿异型住框架楼层变刚度设支撑的设计方法，进行了1／3结构模型试验研究，测试分析了弹性侧移刚度、结构的承载力、延性、滞回曲线、破坏机制及刚度衰减特性。计算所得的结构弹性侧移刚度与实测值符合较好．A. design method is presented for the bracing frame with special-shaped colunms and having rigidity variation along height of the structure. Based on the 1/3 model tests of the structures, study of the lateral elastic rigidity, the bearing capacity, the ductility, the hysteresis loop, the failure meehanism and rigidity attenuhtion characteristic is conducted. The calculation results of lateral elastic rigidity of the structure quite well coincide with the test ones.
