摘要: 近年来,夫板式玻璃幕墙在现代建筑中得到了日益广泛的应用,但对它的理论研究却滞后于工程应用.文中以试验为基础,结合有限元法,研究了不同类型的夹板约束对玻璃板在面内受剪作用下的应力和位移分布规律,以及面内受剪的作用机理,并通过试验数据验证了有限元法的有效性.研究表明:在加载的全过程中,夹板约束玻璃板的位移和应力都随着荷载的增长而线性增长,表现出明显的脆性破坏的特征;面外受弯和面内受剪的作用机理不同,前者是节点区弯拉破坏而后者是玻璃板在支承边界的受压破坏.

Abstract:

In recent years , overlap-connected glass curtain walls have been widely used in the field of modem architecture, but the corresponding theoretical researches lag behind the engineering application. In order to solve this problem , the mechanical behavior and the corresponding mechanism , as well as the stress and displacement distributions of glass panels restrained by different types of overlapped connectors under in-plane shear were investigated by experimental tests and finite element method (FEM). Furthermore , the validity of FEM is experimentally verified. It is concluded that the displacement and stress of the glass panel linearly increase with the shear load in the loading process , and that the panel exhibits significant characteristic of brittle failure. Moreover , the stress mechanism of in-plane shearing is different from that of out-of-plane bending , the former being the compressive failure in contact boundary while the latter being the tensile failure in the joint region.
