用高频动态天平方法研究金茂大厦的动力风荷载和风振响应

Study on Wind Loads and Wind-induced Vibration of the Jin Mao Building Using High-frequency-force-balance Method

上海金茂大厦的总高度为４２０．５ｍ，风荷载是这一超高层建筑的控制荷载。采用目前国际上应用最广泛的高频动态天平方法对这一超高层建筑的模型进行了风洞试验，根据试验结果计算分析了该塔楼在风作用下的动力响应和等效风荷载，并将主要结果和其他有关试验的响应结果进行了对比。

Shanghai Jin Mao Building with a height of 420.5m is at present the tallest building in China and the third tallest in the world.Wind load plays the most important role in the structural design of this building.High-frequency-force-balance technique is widely used for studies on wind-resistant design of tall buildings,and is also used in the present study.The dynamic responses and equivalent wind loads of the Jin Mao Building are obtained based on the experimental results.They are finally compared with the dynamic responses of the building from other research sources.
