型钢混凝土框架滞回性能分析
|
摘要
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 FEM model for the steel reinforced concrete frame was established by the commonly used ABAQUS,the hysteretic behavior of the steel reinforced concrete frame was studied,and the reasonability of the FEM was verified through the contrast with the result obtained in document 11.The influence of factors such as the grade of steel,strength of concrete,axial-load ratio,stirrup ratio and reinforcement ratio on the hysteretic behavior were contrastively and systematically analyzed.The results show that the grade of steel and strength of concrete have a greater influence on the bearing capacity of the structure,but the stirrup ratio and reinforcement ratio have less influence on it.
