Experiment Analysis of Plate Curtain Wall Wind Vibration Response Top Structure of High-rise Building Under Strong Wind Wave

为了降低强风对高层建筑顶部结构飘板幕墙的损坏,延长其使用寿命,对强风下高层建筑顶部结构飘板幕墙风振响应进行了仿真实验。采用风振响应谱的分析方法对飘板幕墙的风振响应进行了分析。通过对8种强风的风速谱、建筑物高度和飘板幕墙梁的刚度这三个变量下获得的飘板幕墙风振响应和风振系数的实验分析,能够得出以下结论:(1)在不同的风速谱下实验得到的飘板幕墙风振响应与风振系数的值存在较大的差异;(2)建筑物高度的不同,飘板幕墙的风振响应也不同;(3)飘板幕墙的风振响应受到结构梁刚度的影响较大,而其风振系数受到结构梁刚度的影响极小。实验结果为高层建筑顶部结构飘板幕墙的设计提供了重要的参考。

In order to reduce the wind structure of high-rise building at the top of the wave plate curtain wall damage, prolong its service life, high-rise building at the top of the structure under strong wind wave plate curtain wall wind vibration response simulation experiment was carried out. The wind vibration response spectrum analysis method for the wind-induced vibration of wave plate curtain wall is analyzed. Through to the eight winds wind velocity spectrum, building height and the rigidity of the floating plate curtain wall beam under the three variables for wind vibration responses of floating plate curtain wall and wind vibration coefficient of experimental analysis, draw the following conclusions：（1）under different wind velocity spectrum experiment for wind vibration responses of floating plate curtain wall and there are many differences between the value of the wind vibration coefficient;（2） building height is different, the wind- induced vibration of wave plate curtain wall is different;（3） the windinduced vibration of wave plate curtain wall is affected by the beam stiffness is bigger, and the wind vibration coefficient is affected by the beam stiffness. The experimental results for the design of the highrise building at the top of the floating plate curtain wall structure provides an important reference.
