青岛万邦中心1#楼高度232.4m,采用钢-混凝土混合结构,体系为混合斜撑框架-核心筒结构。其中,型钢混凝土柱-钢梁-钢斜撑节点为本工程典型节点,受力复杂,对两个1∶4缩尺节点模型进行了试验研究。结果表明,节点核心区在低周往复试验下基本完好,未发生明显剪切破坏;通过对节点的承载力、延性、耗能能力、变形能力的分析评估表明,节点具有良好的承载能力、延性、耗能能力。 Qingdao Wanbang Center 1 # building height 232.4m, the use of steel - concrete hybrid structure, the system for the mixed braced frame - the core tube structure. Among them, the steel-reinforced concrete column-steel beam-steel brace node is a typical node of this project, and its stress is complex. Two models of 1: 4 scale nodes were tested. The results show that the core area of ​​the node is basically intact under the low-cycle reciprocating test, and no obvious shear failure occurs. By analyzing the bearing capacity, ductility, energy dissipation capacity and deformation capacity of the joint, the results show that the node has good bearing capacity, ductility , Energy consumption.
