构件式玻璃幕墙横梁扭转变形分析

玻璃幕墙的横梁受到玻璃重力的偏心压力后,有可能因扭矩导致其外倾扭转,进而影响工程质量。本文针对典型构件式明框玻璃幕墙的横梁扭转,通过实验室检测和有限元仿真研究,分析横梁扭转因素,并提出相关的预防措施。

Torsional deformation may emerge with the beams of glass curtain wall suffering to eccentric distance-eccentricity caused by the glass,which will discount the construction quality.This paper aims at analyzing the deflection of a typical exposed frame supported glass curtain wall,combine laboratory testing and FEA analysis to study this phenomenon.Finally,the factors of this phenomenon were analyzed and some precautionary measures were proposed to guide this case correspondingly.
