钢骨混凝土异形柱正截面承载力及延性计算分析

Calculation and analysis on flexural strength and ductility of special-shaped SRC columns

用条带法对不同轴压比下钢骨混凝土异形柱正截面的承载力和延性进行了计算分析,绘制了相应的M-φ曲线。同时计算分析了在轴压力相同的情况下,随着含钢骨率的变化,钢骨混凝土异形柱承载力和延性的变化情况。文中的结论可供抗震设计参考。

Based on the plane hypothesis, the flexural strength of special-shaped SRC columns is calculated by strip method. The ductility and flexural strength of the special-shaped SRC columns under different axial compression or different steel ratio are analyzed. The M-φ curves are given and some conclusions are proposed as reference for seismic design.
