本文根据四榀柱配有方形螺旋箍筋的弱柱型钢筋混凝土单元框架，在低周反复水平荷载作用下的试验研究，探讨了柱配有方形螺旋箍筋的弱柱型钢筋混凝土框架的延性、滞回性能、耗能能力。并采用静力荷载增量法对框架进行强度分析。
In this paper, based on the experimental study of the weak column reinforced concrete (CFST) frame with quadratic helical stirrup on the quadrangular column, the ductility of the weak column reinforced concrete frame with square spiral stirrups , Hysteresis performance, energy consumption capacity. The strength of the frame is analyzed by static load increment method.
