【摘要】：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。
[Abstract]:In order to reduce the damage caused by the strong wind to the floating slab curtain wall of the top structure of the high-rise building and prolong its service life, The wind vibration response of floating plate curtain wall of high-rise building under strong wind is simulated. The wind vibration response of floating plate curtain wall is analyzed by using the method of wind vibration response spectrum. The wind speed spectrum of 8 kinds of strong wind is analyzed. The experimental analysis of wind-induced vibration response and wind-induced vibration coefficient of floating slab curtain wall is obtained under the three variables of building height and stiffness of floating slab curtain wall beam. The following conclusions can be drawn: (1) there is a great difference between the wind vibration response and the wind vibration coefficient of the floating plate curtain wall under different wind speed spectra) the height of the building is different. The wind-induced vibration response of the floating plate curtain wall is also different from that of the floating plate curtain wall, and the wind-induced vibration response of the floating plate curtain wall is greatly affected by the stiffness of the structure beam. The wind vibration coefficient is minimally affected by the stiffness of the structure beam. The experimental results provide an important reference for the design of the floating slab curtain wall of the top structure of the high-rise building.
