摘要
为了研究钢混凝土组合梁-钢管混凝土柱节点的力学性能和半刚性特性,制作了4个比例为1∶3的节点模型进行试验,借助有限元分析软件ABAQUS建立了节点的有限元模型进行数值计算,分别进行了试验结果与数值计算的相应测点的应变、位移等结果的对比分析.通过试验与数值计算彼此校核,得到了与试验相符的有限元模型.在此模型的基础上,建立了该组合梁柱节点只含几何参数的相对弯矩-转角曲线模型.
In order to deal with mechanical properties and semi-rigid characteristics of joint of steel-concrete composite beam of CFST（concrete-filled steel tubular） column with stiffening ring,the 4 specimens with a scale of 1∶3 are tested by monotonic loading and cyclic loading.The finite element models of the CFST joints are analyzed by the finite element package ABAQUS.The proposed finite element model is validated by comparing the computed values,such as strains and deformations of measuring points,with available experimental results.Based on the models,a relative moment-rotation curve of the joint is proposed.An acceptable correlation is observed through the computed and experimental results obtained from the composite joint.
