方钢管混凝土中节点抗震性能影响因素有限元分析
|
摘要
设计了6个节点模型试件,应用有限元软件ANSYS,对低周反复荷载作用下的节点模型破坏全过程进行分析,并分析芯钢管强度、核心区混凝土强度和外钢管强度对节点滞回性能以及骨架曲线的影响。ANSYS分析结果表明:芯钢管强度和外钢管强度对节点的耗能能力有一定的影响,对节点的承载力影响不大;核心区混凝土的强度对节点的耗能能力和承载力都有一定的影响。
To research the mechanical behavior of the interior joint with core steel tube in Concrete Filled Square Steel Tubular under low reversed cyclic loading,and to explore the relevant factors of the impact of node performance,the whole destruction process of the node model under the action of low cyclic loading was analyzed in the paper based on six designs of the node,by using the finite element software ANSYS.The strength of core steel,the concrete of the core area,the strength of outside steel pipe,the Hysteretic Curve and the skeleton curve on the node model were investigated in details.The results showed that the core strength and outer steel pipe strength have a certain influence on the bearing capacity of the node,but they have little influence on of the energy capacity.And the strength of the concrete of the core area have the impact of the Energy Dissipation and the Bearing Capacity on the node model.
