四点支承玻璃抗风压性能试验研究

本文以某点支式玻璃幕墙工程抗风压性能实验为例，测得了四点支承玻璃的压力差一挠度曲线，并将试验结果与规范JGJ102—2003的计算结果进行比较，对现行规范中四点支承玻璃挠度计算和挠度计算折减系数进行了探讨，为今后规范的进一步完善、修订及四点支承玻璃在点支式幕墙工程中的应用提供了试验依据。

Experimental investigation to wind resistance performance of Four Point-Supported glass

Taking the wind load resistance performance test of one point-supported glass curtain wall engineering as an example,an experimental investigation is made on pressure-deflection of four point-supported glass, and compared result of experiments with calculation result of Criterion JGJ 102-2003. The deflection and four point-supported glass are discussed in the paper. By the more discussion, the work of this paper will be helpful to the further improving of the current code, and there are some test bases for the four point-supported glass application in the point-supported glass curtain wall engineerings.
