[摘要]考虑不同的玻璃板厚度、方形玻璃板边长、矩形玻璃板宽长比、开孔数量、孔心边距和孔径的影响,利用ANSYS软件对点支承幕墙玻璃板进行了计算研究。结果表明:玻璃板的厚度对其强度和刚度都有显著的影响;随着方形玻璃板边长的增大,板中最大拉应力和最大挠度都快速增大;随着矩形玻璃板宽长比的增大,板中最大拉应力和最大挠度都不断增大;六点支撑的玻璃板在相同条件下,板中最大拉应力和最大挠度都比四点支撑的玻璃板小很多;随着孔心边距的增大,玻璃板中最大拉应力和最大挠度均显著减小,但减小的速度会随着孔心边距的增大而放缓;孔边最大拉应力随着孔径的增大而显著减小,但板边中点最大拉应力和挠度以及板心的挠度的减小都十分有限。

Abstract: Considering the impact of the different glass plate thickness, length of square point fixed glass, the ratio of width to length of rectangle plate, holes numbers, hole centre distance and holes radius in glass were also considered. Point fixed glass was studied by ANSYS software. Results show the thickness of glass plate has remarkable influences on the strength and stiffness. The maximal tensile stress and deflection increase quickly with larger size of square plates or ratio of width to length of rectangle plates. Plates with six holes have smaller maximal tensile stress and deflection than plates with four holes under the same other conditions. The maximal tensile stress and deflection decrease quickly with larger hole centre distance and deceleration becomes slow. The largest tensile stress decrease quickly with larger hole radius, but the deflection and the stress on edges of plates decrease slowly.
