| 摘 要： | 某超高层建筑采用斜交网格外筒和钢筋混凝土核心内筒构成的新型筒中筒结构体系,斜交网格外筒由不同角度的矩形钢管混凝土柱斜向相贯而成。为了了解斜交网格外筒平面典型节点实际的受力状况,验证其构造的合理性,对两个相似比为1∶3的平面典型节点模型进行了静力试验,并使用有限元软件ABAQUS对节点模型试验过程进行了数值模拟。结果表明两种加载模式下节点均满足该建筑结构设计承载力的要求,且具有较高的安全性。

| Abstract: | One Super Highrise Building is adopted to a new structural pattern of a reinforced concrete core tube enclosed by an outer lattice tube made of obliquely crossing concrete filled rectangular steel tubular columns.In order to understand the stress state of plannar representative connections used in obliquely crossing lattice and verify the rationality of the details,two 1:3 scale models were respectively applied symmetrical and asymmetrical axial force,and experiment processes were numerical simulated by ABAQUS.The results indicate that the connections are validated to meet the design requirement of the building,with sufficient loading capacity. |
