| 摘 要： | 采用梁柱纤维模型对型钢混凝土梁-角钢混凝土柱组合框架滞回全过程开展数值仿真研究,并与试验结果对比. 在大量参数分析的基础上,探讨了此类组合框架滞回曲线特点,建立了单层单跨组合框架的荷载-位移恢复力模型,该模型可综合考虑轴压比和预应力度等的影响,能对此类组合框架在水平荷载作用下的滞回性能进行预测,其结果与试验及数值仿真结果一致. 相关研究可为简化结构弹塑性动力分析提供参考.

| Abstract: | A hysteretic numerical simulation on the frame structure composed of steel reinforced concrete beams and angle-steel concrete columns was conducted using the beam-column fiber model theory, and compared to the test results. Based on a great number of parameters analysis examples, the characteristics of the hysteretic curves were discussed, and the hysteretic model for single-storey and single-span frame was proposed. This hysteretic model could take the axial compressive ratio and pre-stressing level into account and forecast the hysteretic behavior of the composite frame. Also the results are well agreed with the tests results and numerical simulations, so it could be help for simplifying the elasto-plastic dynamic analysis of the frame structure. |
