摘要
对成都成达大厦跨层巨型斜支撑体系节点的受力特性进行研究。利用整体分析的结果,对典型节点进行壳体有限元建模,对节点区域的应力分布进行有限元分析。通过分析提出节点设计的若干措施。有限元分析表明,所采取的措施可行、有效。
It is researched that the forced features of the joints of the multi-story spanned diagonal bracing system for Chengda Tower in Chengdu. Based on the results of overall structural analysis under various load cases, sectional forces in members, beams, columns and adjacent braces, relating to a certain joint are recorded. Typical joints are then modeled in details for the stress analysis using shell elements. According to the finite element analysis, several measures for joint design are proposed. Subsequent FE analysis indicates that strengthening techniques proposed in this study are feasible and efficient.
