This paper focuses on laminated glass composed of two layers made of tempered glass and an interlayer made of either a totally compliant or a relatively stiff material. The paper demonstrates that discrete element modeling is a viable tool to predict the load–deflection curve from the cracking up to the collapse of laminated glass members, and, hence, to assess the collapse limit states of structural glass. In fact, discrete element modeling may simulate the non-linear composite behavior that the polymeric interlayer and the glass fragments provide a member with, considering the crack patterns of the broken glass, the visco-elasticity of the interlayer, and the structural conditions of the member. The validity of the method is also confirmed through comparisons with other sources — namely, some experiments performed by the authors and an empirical model. The paper presents the method and the results from its application to typical laminated glass members used for structural glass. Those results provide insight into the effects of the design choices on the postbreakage behavior; emphasis is placed on the role played by the type of interlayer.

Fifteen full-scale walls with openings were constructed by professional bricklayers, from recovered bricks and lime-mortar, following ancient rules. Six different FRP reinforcements of the walls were tested. Tests and analyses results show that the in-plane ultimate capacity of the unreinforced walls are extre\uacm-ely greater than seismic codes recognizes; and that FRP reinforcement drastically enhances the in-plane ultimate capacity, but the lateral strength of current codes is significantly lower even than the test results of the same but unreinforced walls

Seismic actions may cause the breakdown of the dowel and aggregate interlocks mechanisms of RC beams, after which the stirrups are the only viable mean of shear resistance. In the zone of the RC beam with vertical cracks, however, also the stirrups do not provide any contribution to the shear capacity. FRP reinforcement epoxy-bonded onto the web is the only viable mean of retrofitting such RC beams, provided that side bonded sheets with diagonal fibers are used. This paper presents a conceptual approach to seismic upgrading. Moreover, this paper presents an analytical model (included all the relevant mathematic) devoted to this special shear state, together with a test (shear failure test of a reinforced beam) and two applications (strengthening of two beams). The model reaches a close expression that predicts the load-carrying capacity of a strengthened beam

The model reproduces the elements responsible for the relative slip between the layers with an elasto-plastic strain-softening interlayer. Further than the slip, the model predicts load induced stress and ultimate load for debonding of the composite beam. The paper presents as well the application of the model to steel-concrete beams, together with the main results and interpretation

The research has included an experimental campaign, which was conducted on Laminated Glass (acronym: LG) subjected to compressive load, and a theoretical analysis, which developed a mathematical model for determining the critical load. The paper shows the experimentation, the model, the simulations of the tests with the model, and a theoretical analysis of products available in the architectural glass marketplace that encompasses glass structural applications. The results show the role of lamination on buckling and provide rules in order to use laminated glass for compressive elements
