摘　　要：通过对 4榀具有同一外形尺寸及配筋而具有不同形式的带有偏心角钢支撑的钢筋混凝土框架和 1榀相同尺寸及配筋的钢筋混凝土框架的对比性试验 ,研究了上述试件的抗侧刚度、极限承载力及结构的耗能等各项指标 ,探讨了偏心角钢支撑钢筋混凝土框架结构的受力特点 。Comparative tests between four RC frames with different forms of eccentric braces of angle steel and one RC portal frame(all the specimens have the same outer dimension and steel ratio) are conducted,by which side stiffness,ultimate bearing capacity and structural energy consumption etc. of the said specimens are studied.The forced characteristics of RC frames with eccentric braces of angle steel are also discussed,and the limit states are analyzed theorectically.
