移动荷载作用下框架节点域内动力响应分析

Dynamic Response Analysis of Framework Node under Mobile Load

利用大型非线性有限元软件ANSYS建立节点实体有限元模型,分析了钢骨混凝土梁-钢管混凝土柱加强环节点在移动荷载作用下的受力机理和动力响应,研究了配骨指标和混凝土强度对节点动力响应的影响,得出节点区在移动荷载作用下的变形图和应力分布图以及位移-时间曲线,速度-时间曲线,从而为节点设计提供依据。

Making the use of large nonlinear finite element software ANSYS establish entity finite element node model, analysis the force mechanism and dynamic response of the steel reinforced concrete beam-steel pipe concrete column node with strengthen links under the mobile load , analysis the impact on node dynamic response which the steel content indicator and concrete strength make, receive the deformation map and the distribution of stress map and displacement-time curve, the velocity-time curve, so as to provide a basis for the node design.
