寒冷地区吊挂式玻璃幕墙裂缝原因分析及预防措施的研究

Analysis of Cracking Causes and Research on Prevention Measures for Hanging-type Glass Curtain Walls in Frigid Regions

在工程事故调查的基础上,通过对吊挂式玻璃幕墙的分析,提出了比较符合实际情况的计算简图,并利用已有的程序对其在不同工况下进行三维有限元分析,找出导致吊挂式玻璃幕墙开裂的主要原因,然后有针对性地提出修改建议。

Based on the investigation of engineering accident, a hanging type glass curtain wall was analyzed and its mechanical model was presented in this article. The main cause of cracking was found by calculating and analyzing the glass curtain wall under all kinds of working load by three dimensional finite element program,and some measures have been taken to improve its mechanical function.
