摘　　要：通过对钢筋混凝土底部矩形柱上部异形柱边框架结构的抗震性能试验研究,分析了该种结构的承载力、刚度及其衰减过程、延性、滞回特性和破坏特征。试验表明,这种框架抗震性能良好。Through experimental research on the seismic behavior of the fringe frame with rectangle columns at the bottom and speciallyshaped columns at upper stories, the author analyzes the bearing capacity, stiffness and its attenuation, ductility, hysteresis property and failure phenomena of the specimen. It is shown that the seismic behavior of this kind of frame is good.
