沿海地区受台风的影响,高层建筑玻璃幕墙容易发生破坏.目前关于玻璃幕墙抗风性能的各种研究方法都具有一定的局限性.在台风登陆时,受大气压变化、温度变化和暴雨的冲击作用的影响幕墙整体会发生振动和变形,使得幕墙玻璃实际的应变和应力分布情况与模型试验和风洞试验的情况大不相同.本文对厦门沿海某高层建筑的玻璃幕墙进行了现场实测研究,获得了台风登陆过程中幕墙玻璃表面的风压情况及大量风致应力数据,并分析了幕墙玻璃上的风压与应力或应变的关系,总结了应力分布情况.
Due to the influence of typhoon in coastal area, the damage to the glass curtain wall of high-rise building is easy to occur.At present, various research methods on the wind-resistance of glass curtain wall have their own limitations.At the time of typhoon landing, under the influence of atmospheric pressure change, temperature change and rainstorm The overall vibration and deformation of the curtain wall will occur, so that the actual strain and stress distribution of the curtain wall glass are very different from those of the model test and the wind tunnel test.In this paper, the field test of the glass curtain wall of a high-rise building in Xiamen coastal area is conducted, The typhoon landing process in the curtain wall surface of the wind pressure and a large number of wind-induced stress data, and analysis of the curtain wall of the wind pressure and the relationship between stress or strain, summed up the stress distribution.
