摘要:

随着建筑科学的发展与工程需求的不断提升,夹层玻璃、真空玻璃等复合玻璃在建筑及相关领域的应用日益广泛。复合玻璃的力学行为较为复杂,通常需采用等效厚度来简化计算分析过程。然而,传统等效厚度计算方法在应对多层结构或特殊构造的复合玻璃时存在一定局限性。为此,本工作提出一种基于对比试验的等效厚度确定方法,通过四点弯曲试验测量在相同支撑和加载条件下单片玻璃与复合玻璃的弯曲应力,依据等效原理计算复合玻璃的等效厚度。结果表明,本方法可同时适用于夹层玻璃、真空玻璃及真空夹层复合玻璃等多种结构。与现行标准规范方法及试验实测值对比,以本方法计算所得的等效厚度具有较高的准确性。本工作还建立了基于夹层梁弯拉强度理论的校核模型,通过理论计算与试验结果的比较,进一步证实了该模型的可靠性。

Abstract:

With the development of architectural science and the continuous improvement of engineering demand, composite glass, such as laminated glass and vacuum glazing, is being increasingly applied in building engineering. The mechanical behaviour of composite glass is complex, equivalent thickness is usually used to simplify the calculation and analysis process, and the current methodologies for determining its effective thickness exhibit limitations when applied to multi?layer or specially configured structures. This paper proposed an experimental method for determining the effective thickness based on comparative tests. Four?point bending tests were conducted to measure the bending stresses of monolithic glass and composite glass under identical loading and supporting conditions. The effective thickness of the composite glass was then calculated through a comparative formulation. The results demonstrate that the proposed method is applicable to various composite glass structures, including laminated glass, vacuum glazing, and vacuum-laminated composite glass. Compared with methods from current standards and measured values of the test show that the obtained effective thickness calculated by this proposed method offers satisfactory accuracy. Furthermore, a theoretical model based on the bending?tensile strength theory of laminated beams was introduced to validate the effective thickness of laminated glass, providing additional confirmation of the proposed method’s reliability.
