低周反复水平荷载作用下柱配有方形螺旋箍筋的钢筋混凝土单元框架抗震性能试验研究

Experimental Research on Seismic Behavior of Concrete Frames with Columns Using Square Spiral Stirrups Under Horizontal Low Cyclic Loading

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。

Based on the experimental results of four single- span, single- story concrete frames with columns using square spiral stirrups under horizontal low cyclic loading and constant vertical loading, the ductility feature, hysteretic characteristics and energy- dissipating capacity of the weak- column type concrete frame with columns using square spiral stirrups are analyzed. The load bearing capacity of this type of frame is calculated by means of the static load incremental analysis method.
