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。
Considering the influence of different thickness of glass plate, the length of square glass plate, the aspect ratio of rectangular glass plate, the number of holes, the center of hole and the diameter of hole, the calculation of point supported curtain glass was carried out by ANSYS software. The results show that the thickness of the glass plate has a significant effect on the strength and stiffness of the glass plate. With the increase of the side length of the square glass plate, the maximum tensile stress and the maximum deflection of the glass plate increase rapidly. The maximum tensile stress and the maximum deflection of the plate are increasing. Under the same conditions, the maximum tensile stress and the maximum deflection of the glass plate supported by the six points are much smaller than those of the glass plate supported by the four points. The increase of the heart margin, the maximum tensile stress and the maximum deflection of the glass plate are significantly reduced, but the reduced velocity will slow down with the increase of the hole center distance. The maximum tensile stress along the hole increases with the increase of the hole diameter Large and significantly reduced, but the maximum bending stress and deflection at the mid-point of the plate and the decrease of the deflection of the plate core are very limited.
