【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 influence of different thickness of glass plate, side length of square glass plate, ratio of width to length of rectangular glass plate, number of holes, hole center margin and aperture, the point supporting curtain wall glass plate was calculated and studied by ANSYS software.The results show that the thickness of the glass plate has a significant effect on its strength and stiffness, the maximum tensile stress and the maximum deflection increase rapidly with the increase of the side length of the square glass plate, and the ratio of width to length increases with the increase of the width ratio of the rectangular glass plate.Under the same conditions, the maximum tensile stress and maximum deflection of the six-point supported glass plate are much smaller than those of the four-point supported glass plate; with the increase of the edge distance between the holes, the maximum tensile stress and the maximum deflection in the plate are increased.The maximum tensile stress and maximum deflection in the glass plate decrease significantly, but the speed of decrease will slow down with the increase of the distance between the center of the hole, and the maximum tensile stress of the hole edge decreases significantly with the increase of the pore diameter.However, the maximum tensile stress and deflection at the midpoint of the plate edge and the reduction of the deflection of the plate center are very limited.
