采用通用有限元程序ABAQUS建立了非线性有限元模型,研究了型钢混凝土框架的滞回性能,通过与文献试验结果的对比分析,验证了有限元模型的合理性。然后就系统的对型钢强度、混凝土强度、配箍率和纵向配筋率等参数对型钢混凝土框架滞回性能的影响进行对比分析。结果表明,型钢强度、混凝土强度对结构承载力影响较大,配箍率、纵向配筋率影响较小。
The nonlinear finite element model was established by the general finite element program ABAQUS, the hysteretic behavior of the SRC frame was studied, and the rationality of the finite element model was verified by comparison with the experimental results of the literature. Then, the influence of parameters such as the strength of steel section, concrete strength, stirrup ratio and longitudinal reinforcement ratio on the hysteretic behavior of SRC frame is compared and analyzed. The results show that the strength of steel and the strength of concrete have a great influence on the bearing capacity of the structure, and the influence of stirrup ratio and longitudinal reinforcement ratio is small.
