| 中文摘要 | 为设计玻璃幕墙结构中的六点支承玻璃板,研究其在面外均布荷载作用下的抗弯承载性能,进行了试验模拟和有限元计算。使用工程中常用的玻璃板材料和紧固件,按照工程实际的安装和支承形式,通过人工施加平面外均布荷载,测量了试件的应力和挠度。试验结果表明:玻璃板的应力和挠度均随着荷载的增加而线性增加,中孔边应力为玻璃板的控制应力,最大挠度在跨中附近,厚板承受面外均布荷载的能力较强。未考虑大变形的有限元计算结果与试验结果吻合相对较好。; The bending resistances of glass panels supported at six points were measured in test and simulated with a finite element model.The test used common materials and support method.The tests measured the stresses and deflections of the glass panels with uniform transverse loads.The results show that the stresses and deflections are linearly related with the external loads.The stress around the middle hole is the controlling stress in the glass panels.The maximum deflection is near the span center and thick glass panels can bear relatively large transverse uniform loads.The finite element results without a large displacement analysis agree well with the test results.The results provide a foundation for the design of six point-supported glass panels.; KGE研究基金资助项目(200401)(横向项目) |
