摘要
节点是结构传递内力的关键环节。本文利用PKPM软件对某高校综合实验楼整体结构进行设计分析,得到桁架部分各个杆件的内力,再运用ANSYS有限元分析软件建立节点有限元模型,将得到的内力施加在节点的实体模型上,分析了节点中混凝土与型钢的应力分布情况和破坏机理以及型钢腹板厚度、混凝土强度等影响参数改变对节点抗剪承载力的影响。
Joint is the key part connecting beams with columns, and the internal force transfer from beam to column through joint. The software PKPM is applied to make statics analysis. The internal force of each component is distilled and brought to the hypostatic model of truss joint in order to make finite element analysis, the stress distribution of eonerete and steel of the joints have been analyzed. The influence of steel web thickness, conerete strength of the joint has been researched.
