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 experiment of wind-pressure resistance of single curtain wall of a building as an example, the pressure difference-deflection curve between single-layer glass and insulating glass in the same unit was measured. The test results were compared with the calculation of JGJ 102-2003 Technical Specifications for Glass Curtain Wall The results are compared. The calculation of the glass deflection in the code η on the same conditions, the impact of single-layer glass and insulating glass were discussed, and the value of insulating glass thickness was corrected, given the correction factor for the future specification further Improve and revise a number of discussions.
