摘要(Abstract):
面内受弯玻璃板经常被应用于玻璃承重结构中,这种板件在不同的支承情况下会有不同的力学响应,而且当缺少足够的侧向支承时,板件还会发生整体失稳而破坏,现有的玻璃幕墙规范对这种结构没有相关的规定。采用有限元方法分析了面内受弯玻璃板静力承载性能的两个主要影响因素——板厚和跨高比,并对不同荷载状况下两种常见类型玻璃板的稳定问题进行分析,得到了其屈曲荷载及屈曲模态。
In-plane bending glass plate is more and more widely used as a sort of load bearing glass structure,which behaves differently under different supporting conditions.If there aren't enough supports,the plates may lose the resistance to overturning.In current code of curtain wall,the problems of stress and displacement of in-plane bending glass plate haven't been solved.Two main influencing factors of static bearing properties of in-plane bending glass plate which are thickness and length-width ratio,are analyzed.The buckling problems of two common in-plane bending glass plate are discussed,and the buckling loads and buckling modes are obtained.
