摘要
建立了有广泛代表性的钢框架加腋节点的三维有限元模型,对其进行了非线性分析.绘制了加腋节点中关键部位的应力分布图,对比地分析了加腋节点和普通节点中各种应力分布规律;并利用Ansys的立体切片显示功能,沿着定义的路径来分析应力分布,判断加腋后对节点应力的影响.
The representative 3D FEA-model of haunched node of steel moment-resisting frame is set up and it is analyzed nonlinearly.The characteristic of stress distribution in connection is expounded and the stress distribution rules in haunched node and ordinary node are compared.Then the stress distribution is analysed along the definite path to judge the influence on the post-haunched node by using the displayed function of Ansys tridimensional section.
