矩形驳接单层索网玻璃幕墙协同工作下的整体结构受力分析

Whole structure's mechanical analysis under single-layer cable net for rectangle connector-supporting working in coordination

目前,单层索网玻璃幕墙在现代建筑中得到了日益广泛的应用,其整体结构受力研究通常采用拉索与玻璃分开进行分析。本文利用有限元3D实体模型,考虑了竖向与横向预应力拉索非平面及矩形驳接件与玻璃之间的作用,设置了玻璃厚度、竖向预应力索与玻璃间距、竖向索与横向索间距、索直径和预应力等参数,在风荷载和自重荷载共同作用下,对矩形驳接单层索网玻璃幕墙协同工作下的整体结构,在各种参数下进行了受力有限元分析,并与以通常计算方式所计算的结果进行了比较,为进一步完善点式玻璃的设计和在实际工程中单层索网玻璃幕墙进行整体进行受力分析提供了依据。

At the present time, the single-layer cable net glass curtain wall has been widely used in the field of modern architecture, and the analysis of its mechanics has been analyzed by the cable without consideration of the glass. Based on the vertical ＆ horizontal prestressed cable＇s nonplanarness and the function between the rectangular connector and the glass in the 3D FEA solid models, the paper makes the different parameters, such as glass thickness, distance between vertical prestressed cable and glass, distance between vertical cable and horizontal cable, cable diameter and cable prestress. Under the single-layer cable net for the rectangle connector-supporting working in coordination, the whole structure is analyzed by the different parameters＇ changing in the function of the wind-load and deadweight-load, and the FEA results compare with the design method for the point-supported glass curtain wall＇s panel. The conclusions are offered for the future designs of the single-layer cable net for the rectangle connector-supporting glass curtain wall and the whole analysis of the practical engineering.
