摘要
以某大厦单元式幕墙抗风压性能实验为例,测得了同一单元中单层玻璃与中空玻璃的压力差—挠度曲线,并将试验结果与JGJ 102-2003《玻璃幕墙工程技术规范》的计算结果进行比较。对该规范中玻璃挠度计算折减系数η对同等条件下单层玻璃和中空玻璃影响进行了探讨,并对中空玻璃等效厚度取值进行了修正,给出了修正系数,为今后规范的进一步完善和修订做了一些探讨工作。
Taking the wind load resistance performance test of some high-rise＇s curtain wall as an example,an experimental investigation is made on pressure-deflection of single-layer and insulating glass,and compared result of experiments with calculation result of Criterion JGJ 102—2003.In the code the η to single-layer and insulating glass is discussed under the same conditions,and the value of equivalent thickness of insulating glass given is revised and corresponding revised coefficient is given.The paper is done some exploratory work for the further refined and revised code.
