Simulation of Reinforced Concrete T-joints Displacement Limits

在各种载荷工况下,对钢筋混凝土梁柱节点进行受力分析比较困难。为此,对梁柱节点的静力学特性进行了仿真分析。采用有限元对梁柱节点的整体进行了静力学分析和简化;利用ANSYS分析软件,依据有限元理论对实际结构进行了合理的力学简化;通过建模、材料属性、约束、加载等程序,利用APDL语言编程,对梁柱节点进行了载荷受力仿真分析,分析了整体结构变形和应力分布,并对其仿真模拟值进行了验证。研究结果表明:变形与应力仿真模拟值与ANSYS Inc.模拟值和实测值三者的吻合度非常高,表明此种模拟计算方法契合实际钢筋混凝土节点,可靠性较高;该结果可以为此类构件进行优化奠定基础。

Under various load conditions, it is difficult to perform stress analysis on reinforced concrete beam-column joints. For this reason, the statics characteristics of beam-column joints are simulated and analyzed. The static analysis and simplification of the whole beam-column joint is carried out by using finite element;the rational mechanical simplification of the actual structure is carried out according to the finite element theory by using ANSYS analysis software. By using modeling, material properties, constraints, loading and other programs, and using APDL language programming, the load and force simulation analysis of beam-column joints is carried out. The overall structural deformation and stress distribution are analyzed, and their simulation values are verified. The research results show that the simulation value of deformation and stress has a very high degree of agreement with the simulation value and the measured value of ANSYS Inc., indicating that this simulation calculation method is suitable for the actual reinforced concrete joint and has high reliability. The results can lay the foundation for the optimization of such components.
