青岛万邦中心1#楼高度为232.4m,采用钢-混凝土混合结构,整体体系为斜撑框架-核心筒结构。其中,地上层10一个角柱由倒Y形空间斜柱转换结构承托,其受力复杂,节点区焊缝较多,为验证其受力性能,采用两个1∶5缩尺节点模型进行试验研究。结果表明转换节点的核心区未出现明显破坏,主要转换构件处于弹性状态且应力水平较低,主要破坏发生于钢梁端部,说明钢端是节点中的薄弱环节,且受力十分复杂,最终设计加大了梁截面。
Qingdao Wanbang Center 1 # building height of 232.4m, the use of steel - concrete hybrid structure, the overall system for the bracing frame - the core tube structure. Among them, one corner column of the ground floor 10 is supported by an inverted Y-shaped space inclined column conversion structure, and its force is complicated. There are many weld joints in the node area. To verify its mechanical performance, two 1: 5 scale node models are used for testing the study. The results show that there is no obvious damage in the core of the transfer node, the main conversion member is in the elastic state and the stress level is low, and the main damage occurs at the end of the steel beam, indicating that the steel end is the weak link in the node and the force is very complicated. Design to increase the beam section.
