This paper focus on bearing capacity and failure mode of monolithic and laminated glass plates with one-way supported conditions under quasi-static local uniform pressure. The results found that the load-displacement relationship of the two kinds of glasses in the loading stage were nearly linear and both of them had obviously brittle failure characteristics. It was found that the PVB interlayer had a significant effect on bearing capacity and failure mode of laminated glass. When reached the bearing capacity limit, the monolithic glass instantly split into pieces and the debris flew around with very high speed while the laminated glasses had only one piece of glasses cracked firstly and the whole laminated glass still had certain bearing capacity. The results show that the monolithic glass cannot be used as the bridge deck, however, the reasonable designed laminated glass has high bearing capacity and does not hurt people when cracked. So the laminated glass can be considered as the safety glass for the vehicle bridge deck.

Under the impact of external shock, even if the glass is broken, the debris will be stuck in the middle film, and it will not fly away. Due to the safety damage characteristics, laminated glass is widely used in automotive, aviation and construction fields (Aktaş et al. 2013, Timmel et al. 2007, Zhang et al. 2013). In recently, in order to get a thrilling, exciting building effect, there are more and more glass buildings were constructed with glass as main force structure, such as glass floor, glass staircase, glass plank road, glass suspension bridge, etc. (Weller and Engelmann 2016). In modern automobile marketing centers and urban three-dimensional parking lots and other projects, because of lighting and landscape needs, the glass bridge deck has attracted great interest from engineers. The bearing glass panels are usually intercalated laminated glass, that is, using the middle film to glue more than two toughened glass into a safety glass. A large number of literatures have been carried out to study the load carrying capacity and cracking performance of laminated glass under static or dynamic loading (Galuppi et al. 2013a, 2013b, Zemanová et al. 2014). The focus of experiment studies were mainly concentrated on the research of the bearing capacity of four dimensions simply supported or point supported glass curtain walls under uniform load and the research on the mechanical properties of glass beams (Belis et al. 2013, Huang et al. 2016, Xu et al. 2011, Yeganeh et al. 2015). The maximum bearing capacity under different parameters such as size, thickness and width to thickness ratio were obtained, then they were used as the design basis for designing glass curtain wall and other bearing glasses (Galuppi and Royer-Carfagni 2012, López-Aenlle et al. 2013). In theoretical researches, the numerical simulation method of laminated glasses and the effect of PVB interlayer on the bearing capacity of laminated glasses were mainly studied (Huang et al. 2015, Ivanov et al. 2016, Nawar et al. 2016). The PVB material simulation method has undergone the development from the earliest linear elasticity to elastoplasticity and lastly to viscoelasticity. Alex Van Duser etc. firstly used viscoelastic model to simulate the PVB material, and the mechanical
