台风作用下某空中连廊结构风振响应研究

Study on Wind-induced Vibration Response of a Sky Bridge Structure Under Typhoon

以厦门市国贸金融中心为研究对象,利用台风"白鹿"过境期间记录的相关实测数据,计算了该高层建筑在强风下的风振响应。依据建筑顶层风速仪记录的风速数据,采用谐波叠加法模拟了该建筑周围的风场,建立结构有限元模型,模拟了建筑在台风环境下的加速度和应变响应,将模拟的响应与实测的数据进行对比,表明了风振响应分析方法具有适用性。

Taking Xiamen International Trade Financial Center as the research object,wecalculated the wind-induced vibration response of the high-rise building under strong wind by using the relevant measured data recorded during the transit period of typhoon Bailu.According to the wind speed data recorded by the anemometers which was installed on the roof of the building,the wind field around the building was simulated using weighted amplitude wave superposition method(WAWS),and the structural finite element model was established to simulate the acceleration and strain response of the building in typhoon wind field.The comparison between the simulated response and the measured response shows that the analysis method for wind-induced response is applicable.
