摘要
通过模拟地震作用,对受低周循环荷载的混凝土框架中节点做粘钢加固前后的ANSYS有限元数值模拟分析,并将数值模拟结果与实验数据进行对比分析,在验证了有限元模型正确的基础上,通过改变加固钢材的厚度,建立了M1,M2,M3,M4四个模型,讨论了加固不同厚度柱部角钢、梁上钢板、梁柱核心区箍板对节点受力的影响,以及加固板厚对节点滞回曲线的影响,得出结论。
The simulation of seismic cyclic loading by low-cycle nodes concrete frame strengthened by steel plate made before and after the ANSYS finite element numerical simulation analysis, and simulation results are compared with the experimental data analysis in the verified finite element model based on the right, by changing the thickness of the steel reinforcement, the establishment of a M1, M2, M3, M4 in four models, a department of reinforcement column angle, beam reinforcement plate, beam reinforcement plate to the hoop joint of the impact and reinforcement thickness on the hysteretic curves, the impact of energy consumption, useful conclusions are obtained.
