摘　　要：在点式支承玻璃建筑中 ,很多情况下玻璃板不仅要承受弯曲荷载如风荷载的作用 ,还要承受剪切荷载如重力的作用。另外 ,温度、支座位移等因素也可能引起较大的面内剪力。根据有限元计算结果 ,分析了四点简支单片玻璃板在面内剪力作用下的应力分布情况 ,具体考虑了孔心边距、剪力大小、玻璃板尺寸以及厚度等因素的改变对孔边应力产生的影响 ,给出了点支承玻璃板抵抗面内剪力时的设计建议。In the point-supporting glass structures,the glass planes are supposed to bear both the bending load such as wind load and the shear load such as gravity.Add itionally,it is possible to generate shearing force by some factors like the ch ange of temperature or support displacement.According to the results of finite e lement calculations,the effects of the distance from the center of the hole to t he edge of the glass,the shear force,the section and thickness of glass on the m aximum stress near the holes in the glass are researched.Some conclusions and ad vices are drawn from the analysis.
