摘要:
针对应用于玻璃楼梯、玻璃楼板等承载玻璃结构中的T型组合受弯玻璃板,在特定的条件下结构会发生整体失稳而破坏,其承载力由屈曲荷载控制,而现有的玻璃幕墙规范中对这种结构形式没有相关规定的问题,采用有限元方法分析了不同参数对T型组合受弯玻璃板静力承载性能的影响,并对不同荷载状况下T型组合受弯玻璃板的稳定性问题进行分析,得到了其屈曲荷载及屈曲模态。计算结果表明:影响T型组合受弯玻璃板静力承载性能的主要因素为板厚、肋板高度和翼缘板宽度,而影响其稳定性的主要因素为肋板高度和翼缘板宽度的比值。
Abstract:
T-type combined bending glass plate is more and more widely used in load bearing glass structure, such as glass stair and glass floor. Global buckling occurs under certain conditions and leads to structure damage, andthe bearing capacity is defined by the buckling load, however current code hasnot specified the design method for this structure. Finite element method was used to do parametric analysis on T-type combined bending glassplate static bearing properties; meantime stabilization problems under different load cases were studied and buckling loads; buckling modes were obtained. The calculation results prove that the main factors affect the load bearing properties of this structure including the thickness of plate, height of glass riband width of cover plate, and the main factor affected stability is ratio of width of glass rib to width of flange dominated the stabilization properties most.
