【摘要】 为了系统全面地对比不同构造形式加强型节点的力学性能,采用ANSYS对四种加强型节点及普通节点进行有限元模拟,并结合相关试验结果验证了有限元分析的可靠性,综合对比分析了节点模型的破坏形态、滞回性能、承载力、延性系数及耗能能力。分析结果表明,加强型节点能有效地提高节点的承载力,达到塑性铰外移的目的,滞回曲线饱满,并且具有良好的延性及耗能能力,其中翼缘板加强型节点和直接扩翼型节点综合性能最好。更多还原

【Abstract】 In order to compare the mechanical properties of different structural forms of reinforced nodes systematically and comprehensively,using ANSYS on four reinforced nodes and one ordinary node to make finite element simulation.Relevant nodes experiments are combined to validate the reliability of finite element analysis.Failure modes,hysteretic behavior,bearing capacity,ductility and energy dissipation capacity of models are analyzed comprehensively and comparatively.The results showed that reinforced node can improve the bearing capacity effectively to achieve the purpose of the relocation of the plastic hinge,they all have full hysteretic curve,and have good ductility and energy dissipation capacity.The comprehensive performance of flange-plate reinforced node and widen flange node are best of all.更多还原
