摘要:
基于试验研究，采用 OpenSees 系统对型钢混凝土(SRC)异形柱 的滞回性能进行有限元模拟，计算结果与试验结果吻 合较好．根据计算结果，获得了柱端的弯矩-曲率滞回曲线，分析了P-Δ效应的影响和耗能能力．结果表明：SRC 异形柱的滞回曲线饱满对称；P-Δ效应使SRC异形柱的承载力降低3.2%～12.4%，延性变差；与钢筋混凝土异形柱相比，SRC异形柱的能量耗散系数大，耗能能力强；实腹式配钢试件的滞回性能优于空腹式配钢试件．研究为SRC 异形柱的工程应用提供参考．
Abstract:
Based on the experimental study, the finite element simulation of the hysteretic behavior of steel reinforced concrete (SRC) special-shaped column was conducted by OpenSees. The moment-curvature hysteretic loops of column end were obtained, and the influence of P-Δ effect and energy dissipation were analyzed. Results show calculated that the hysteretic loops of SRC special-shaped columns are symmetric and plump. P-Δ effect results in that the load bearing capacity of SRC special-shaped column reduces by 3.2%～12.4%, and the ductility turns worse. Compared with the reinforced concrete special-shaped column, the energy dissipation coefficient is large, showing the strong capacity of energy dissipation. The hysteretic performance of the column with solid steel is superior to that of the column with lattice steel. This study can provide reference for practical engineering application of SRC special-shaped column.
