摘要
文中利用ABAQUS对多层框架结构中存在空鼓的内隔板式矩形钢管混凝土柱-H型钢梁边跨节点,从钢管壁厚、轴压比两个变量因素进行模拟对比分析研究,结果表明在弹性阶段范围内,节点随着钢管壁厚的增加,钢管混凝土柱对边存在空鼓的试件的刚度逐渐增加,承载力有所提高;节点随着轴压比的增加,极限承载力、强度、刚度、抗震性能有所减弱,但是延性变形能力稍有增加。
In terms of the steel tube wall thickness and axial compression ratio,this paper uses ABAQUS software to analyze the side-span joints betweenthe inner bulkhead rectangular steel tube with hollow drumsand concrete column-H-shaped steel beams in the multilayer frame structure.The results show that as the thickness of the steel tube wall increases,the stiffness of the test piece with hollow drums on the opposite side of the steel tube concrete column gradually increases,and the bearing capacity increases within the elastic stage.As the axial compression ratio increases,the ultimate bearing capacity of the node increases,whereas,the strength,the stiffness,and the seismic performance weakened,andthe ductile deformation capacity increased slightly.
