摘要
钢筋混凝土框架节点的传力机理历来存在分歧,由试验又不能测量节点区混凝土各部分应力应变。运用有限元分析程序得出的节点区混凝土的应力应变分布,结合节点试验结果对节点传力机理进行了分析,探讨了何种现有传力机理理论更加合理。
There are different theories about the load transformation of R C frame joints. It＇s hard for joint experiments to measure the stress and strain of concrete inside the joint. With FEM program＇s help, we can get the stress distribution of concrete. Use both the experiments＇ results and the FEM program results to find out which theory can explain the results better.
