摘要
针对某地下车站主体结构中应用的钢管混凝土柱-型钢混凝土梁加强环式节点,根据相似原理对其进行静力试验研究,通过试验了解此节点的承载能力和破坏机理;进而利用ANSYS有限元分析软件对此试件进行了非线性数值模拟,对试验和理论结果对比研究分析表明,该节点传力路线明确,受力性能良好,满足"强节点,弱构件"的设计要求。
In this paper, based on the principle of similitude ,joint of SRC Beam-CFST Column with ring stiffeners of the underground station is investigated. Based on monotonic loading experimental investigation, the failure mechanism and ultimate bearing capacity of SRC Beam-CFST Column Connection are analyzed, then 3D nonlinear finite element models were used to analyze the mechanical properties of this SRC Beam-CFST Column Connection using ANSYS. The analyses of the experimental and theoretical resuits show that this type joint performs well work behavior and is reliable to capacity.
