摘要/Abstract

摘要： 窄腔室薄型中空玻璃(TC-IG)为典型的双腔结构,其承载变形性能影响因素较为复杂,中片玻璃的变形及强度也存在明显厚度效应。本文采用ABAQUS有限元分析软件,对窄腔室薄型中空玻璃进行实体建模,研究风荷载作用下玻璃厚度和风荷载大小对窄腔室薄型中空玻璃位移、最大主应力及荷载分配比例的影响规律。结果表明:风荷载作用下窄腔室薄型中空玻璃各片玻璃最大位移均位于板心位置,并向玻璃四周均匀减小,随着中片玻璃厚度减薄,外、内片玻璃最大位移增大,中片玻璃最大位移先增大后减小;中片玻璃最大主应力小于外、内片玻璃,随着中片玻璃厚度减薄,外、内片玻璃最大主应力增大,中片玻璃最大主应力减小;随着风荷载增大,中片玻璃最大主应力最大值从板心及附近位置向四角位置移动,中片玻璃厚度越薄,最大主应力最大值越靠近四角位置,可能成为高风荷载下中片玻璃断裂起始点;窄腔室薄型中空玻璃各片玻璃风荷载分配比例主要与中片玻璃厚度有关,当外、内片玻璃厚度不变时,中片玻璃厚度越薄其荷载分配比例越低,外、内片玻璃成为风荷载的主要承担部分。

Abstract: Thin-chamber insulating glazing (TC-IG) possesses a typical double cavity structure, and the influencing factors of its load-bearing deformation performance are more complex. Moreover, the deformation and strength of middle glass also exhibits the significant thickness effects. In this paper, ABAQUS finite element analysis software was used to build a solid modeling of TC-IG, and the effects of glass thickness and wind load on the displacement, maximum principal stress and load distribution ratio of TC-IG under wind load are studied. The results show that the maximum displacement of each piece glass of TC-IG locates at the center of the plate and decreases uniformly around the glass under wind load. With the thickness of middle glass decreases, the maximum displacements of the outer and inner glasses increase, and the maximum displacement of the middle glass first increases and then decreases. The maximum principal stress of the middle glass is lower than that of the outer and inner glasses. With the thickness of the middle glass decreases, the maximum principal stress of the outer and inner glasses increases, while the maximum principal stress of the middle glass decreases. With the wind load increase, the maximum principal stress of the middle glass is shifted from the center of the plate and nearby positions to the four corner positions. The thinner the thickness of the middle glass is, the closer the maximum value of the maximum principal stress is to the four corner positions, which may become the starting point of fracture of the middle glass under high wind load. The wind load distribution ratio of each piece glass of TC-IG is mainly related to the thickness of the middle glass. When the thickness of the outer and inner glass is constant, the thinner the thickness of the middle glass is, the lower the load distribution ratio is, and the outer and inner glass become the main part of the wind load.
