［摘要］考慮不同的玻璃板厚度、方形玻璃板邊長、矩形玻璃板寬長比、開孔數(shù)量、孔心邊距和孔徑的影響，利用ANSYS軟件對點支承幕墻玻璃板進行了計算研究。結(jié)果表明：玻璃板的厚度對其強度和剛度都有顯著的影響；隨著方形玻璃板邊長的增大，板中最大拉應(yīng)力和最大撓度都快速增大；隨著矩形玻璃板寬長比的增大，板中最大拉應(yīng)力和最大撓度都不斷增大；六點支撐的玻璃板在相同條件下，板中最大拉應(yīng)力和最大撓度都比四點支撐的玻璃板小很多；隨著孔心邊距的增大，玻璃板中最大拉應(yīng)力和最大撓度均顯著減小，但減小的速度會隨著孔心邊距的增大而放緩；孔邊最大拉應(yīng)力隨著孔徑的增大而顯著減小，但板邊中點最大拉應(yīng)力和撓度以及板心的撓度的減小都十分有限。

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.
Keywords: point fixed curtain wall; glass plate; finite element method; stress; displacement
