摘要
广州塔总高600m,为目前世界最高的电视塔。利用ANSYS计算模型对广州塔结构进行了稳定性分析,找到了影响结构稳定性的主要因素,即外框筒节点刚度和透空区长度。通过对比分析,提出了外框筒刚性节点设计要求和合理的透空区支撑布置方式,并采用考虑初始缺陷的非线性稳定分析方法对结构进行了稳定分析。通过试验验证了设计的合理性,保证了结构的安全性。
Guangzhou Tower is 600m high, which is the tallest TV tower in the word at present. It is found that the joint rigidity of out-frame tube and the length of un-braced zone are the major factors that influence the structural stability according to structural stability analysis by the ANSYS. Based on the comparative analysis, the design requirement of joint rigidity of out-frame tube and reasonable bracing arrangement were presented. Also, nonlinear stability analysis considering initial defect and tests were performed to guarantee the safety of the structure.
