Analysis on Loading Capacity of Six Point-Supported Glass Panel

摘要

Point-supported glass panels are widely applied in glass curtain wall structure. Six point-supported glass panels can be utilized if the dimension of glass panels is relatively large. However,in current technical code for glass curtain wall engineering the design formulas for the stress and deflection of six point-supported glass panels have not been presented. Besides, the pattern of point-supported glass panels will bring concentrative stress near the hole under load, and the fine cracks made by drilling will reduqe the intensity around the hole. So it is necessary to analyze the stress near the hole as well as the glass panel stress. This paper mainly analyzes the loading capacity of six point-supported glass panels by means of finite element method, considering such variable factors as the supporting condition of the glass panel,the distance from the hole center to the glass panel edge,the thickness and the dimension of the glass panel,and the supporting point displacement, all of which are relative to the stress and deflection of the glass panel,then brings forward the law between the stress as well as the deflection of the glass panel and the variable factors mentioned above.
