| 摘 要： | 为了了解不同类型夹板约束玻璃板和点支式在面外载荷作用下受弯的全过程中,应力和位移的发展以及极限破坏载荷,以试验为基础,结合有限元方法,对该类玻璃板进行了研究,并给出了玻璃板载荷位移以及最大主应力载荷的全过程曲线:比较了夹板约束玻璃板和点支式玻璃板受力性能的不同;通过试验数据验证了有限元方法应用于玻璃板承载力验算的有效性.试验表明,夹板式玻璃板和点支式玻璃板在面外受弯下位移和应力与面外载荷是线性关系;对于相同的玻璃板,节点连接方式不同,其破坏载倚可能有较大的差别;将节点区最大应力作为整体最大应力的控制点是合适的.

| Abstract: | Based on the experimental test and FEM analysis,glass panels with different types of overlapped connector and point supported glass panel are investigated to understand the development of stress and displacement and limit load under bending out of plane.Firstly,the load-displacement and maximal stress-load curve are suggested;second,bending properties between overlap-connected and point supported glass panels are compared;finally,the validity of application of FEM in glass panel is proved by data from exper... |
