响应面法在玻璃幕墙可靠度分析中的应用

Reliability analysis of glass curtain wall under effect of typhoon

玻璃幕墙结构在台风作用下,常常发生破环和脱落,造成经济损失,严重威胁人民的生命财产安全。在易受台风袭击的沿海城市,对玻璃幕墙进行各种可靠度的研究和分析,是幕墙抗风设计中的一项重要内容,为工程施工提供可靠的理论依据。根据玻璃幕墙结构可靠度研究进展和台风的特性,将二次多项式序列响应面方法引入玻璃幕墙台风作用下的可靠度分析,采用基于石沅台风风谱的时程风载进行结构分析和计算,得出台风作用下的可靠度指标,并与一次二阶矩法和蒙特卡洛方法进行对比,得出一些重要的结论。

At typhoons affect inferior,glass curtain wall frequently occurring breaking ring abscisic damage equal phenomenon,engender every kind of engineering accidents.So at easy of coastal urban,glass curtain wall proceed every kind of reliability of study on and analysis shall right and wrong constant value study on of problem.The text comprehensive review end deconstruction reliability study on of every kind of method,and adopted quadratic polynomial sequential response surface method solving glass curtain wall reliability and failure probability.Depended on wind loads loading middle adopt the based on stone typhoons wind spectrum of time wind load proceed structure analysis and calculation.
