Architectural soda-lime silicate glass (SLS) is increasingly taking on complex shapes that require more detailed numerical analysis. Glass modeling is a thoroughly described topic with validated constitutive models. However, these models require a number of precise material parameters for SLS glass, and these are very sensitive to changes in glass composition. The currently available information is based on SLS glass tested in the late 1990s. As a result, most current publications are based on the above data. The object of this work was to analyze the available sources and update the information on selected key parameters for modeling. Using the currently utilized SLS glass in construction, the coefficient of thermal expansion (CTE), glass transition temperature, and the Young's modulus have been experimentally investigated. The updated material parameters will allow for more accurate modeling of the SLS glass currently used in construction, and in consequence will make the prototyping process for glass with complex geometries possible to be transferred from the production stage to the design stage, resulting in shorter production times.
建筑用钠钙硅酸盐玻璃（SLS）正越来越多地呈现出复杂形状，这需要更详细的数值分析。玻璃建模是一个有充分描述且具有经过验证的本构模型的主题。然而，这些模型需要大量关于SLS玻璃的精确材料参数，并且这些参数对玻璃成分的变化非常敏感。目前可用的信息基于20世纪90年代末测试的SLS玻璃。因此，当前的大多数出版物都基于上述数据。这项工作的目的是分析可用来源并更新建模所需的选定关键参数的信息。使用建筑中目前使用的SLS玻璃，对热膨胀系数（CTE）、玻璃化转变温度和杨氏模量进行了实验研究。更新后的材料参数将使目前建筑中使用的SLS玻璃能够进行更精确的建模，从而使具有复杂几何形状的玻璃原型制作过程有可能从生产阶段转移到设计阶段，进而缩短生产时间。
