摘要
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。
Field measurement data are base of the research of wind-resistance on structures.Based on the wind-induced displacement response from field measurement on Jin Mao Tower under the Typhoon Matsa,2005,the corresponding equivalent static wind loads of Typhoon Matsa were predicted from the calculation model.These results were compared with ESWL from wind tunnel tests.Some parameters such as wind profile,damping ratio were discussed in order to check the reasonableness of wind parameters in the designing Jin Mao Tower.
