实测数据是所有结构抗风研究的基础,以2005年麦莎台风下实测位移响应为基础,反演计算台风作用时的等效静力风荷载,通过对比风洞试验结果,对金茂大厦在强风作用下的响应及等效静力风荷载进行了较全面的分析,并对风剖面、阻尼比等响应风荷载的参数进行讨论,以此检验金茂大厦设计中所采用的抗风设计参数的合理性,通过实测数据的研究分析为超高层建筑抗风设计提供参考意见。
The measured data are the foundation for wind-resistance study of all structures. Based on the measured displacement response under the typhoon Matsa in 2005, the equivalent static wind load is calculated by back analysis when the typhoon is acting. By comparing the wind tunnel test results, The response under strong wind and equivalent static wind load are analyzed comprehensively and the parameters of wind response such as wind profile and damping ratio are discussed to test the wind resistance design parameters used in the design of Jin Mao Tower The rationality of this study provides reference for wind-resistance design of super high-rise buildings through the research and analysis of measured data.
