中空玻璃应力计算理论研究

Research of the Calculation Theory of the Hollow Glass

中空玻璃已经被广泛应用到建筑外围装饰结构中,目前对于幕墙玻璃的设计方法,其中一种是将其看作一个整体模型,利用等效厚度的概念进行计算,对于整体模型的位移计算采用这种方法是可行的,但是对于玻璃应力却产生了较大的误差,这是由于等效厚度是根据位移相等得到的,应用在应力计算中却失去了原来的理论意义。

The laminated safety glass and hollow glass have widespread availabilities in the decorative construction.In the design methods of the glass plate ,one of those is to calculate the stresses and the deflection with the equivalent thickness as an integral model.It is effective for the defection calculation,but make an large error when applied in the stresses calculation.It is because the equivalent thickness which divides from the equal deflection model is meaningless in the stress calculation.
