Effect of Novel Thermo-Chemical Treatment on Bending Strength of Laminated Glass

Many examples of glass loadbearing structures such as handrails, panes, beams and columns can be found in modern architecture. Most of these elements are made of laminated glass panels. There is a general lack of knowledge about the transfer of shear forces between the glass plies in perpendicularly-loaded laminated panels. This transfer depends significantly on the stiffness of the polymeric interlayer, which is timedependent and temperature-dependent. There are several computational methods for the design of laminated glass that take the shear coupling of the glass plies into account, e.g. analytical methods, numerical modeling and also the draft of European code. These methods need to be verified experimentally. This paper reports on rectangular double-laminated glass panels in a shortterm displacement controlled four-point bending test with an EVA and with a PVB interlayer under a constant temperature. These tests were performed at CTU in Prague. Our experimental results show that panels with an EVA interlayer had greater bending stiffness than panels laminated with PVB and achieved higher ultimate load values. The experimental data were further compared with simplified analytical methods, such as the European draft prEN 16612 and the Enhanced Effective Thickness approach and also a numerical FEM model. Numerical and EET methods results were in good agreement with the experimental data. The way in which the specimens broke was a characteristic feature of laminated glass. The shards remained attached to the interlayer, proving that laminated glass panels can be used safely above the heads of users of the structure. Simplified methods and numerical models validated by experimental tests on perpendicularly-loaded laminated glass panels enable these structures to be designed safely and economically for practical uses.

“…The paper aims at presenting some original studies on the melt flow, melting and rheology. Vedrtnam (2018) focuses on the flexural performance of laminated glass members and proves the efficiency of novel treatment methods to improve the mechanical parameters (especially the material resistance) of ordinary glass. Also (Hána et al, 2018) investigate the bending and structural response of laminated glass members with different interlayers.…”

The year 2018 starts with a great confirmation for SGAMR!The journal has been selected to host the extended version of some selected papers presented during the 6 th International Workshop on Design in Civil and Environmental Engineering (DCEE2017), held at the University of Cagliari (Italy) during November 2017. A summary of selected papers from highly ranked, international scientists can be found in (Bedon et al., 2018a). Among the submitted contributors, the covered topics are various and equally important for the science and knowledge development and include an insight on innovative reinforcement techniques for masonry walls (Akhoundi et al., 2018) the design of a multifunctional hybrid steel-glass structure (Froli and Laccone, 2018); the application of diagnostic surveying to existing buildings (Concu et al., 2018) the nonlinear behaviour of RC culverts on elastic soil (Baraldi et al., 2018). The application of infrared thermography approaches for the characterization of painted masonry vaults in historical buildings is proposed by (Casapulla et al., 2018). Valdés et al. (2018) focus on the characterization of recycled thermoplastic timber and its efficient mechanical use in buildings. Zucca et al. (2018) discuss about the definition/scheduling of the best timing and execution activities for a new mixed structure building in Milano. Deligia et al. (2018), finally, presents the final outcomes of the "Didactic Laboratory of Theory and Design of Structures", from the Bachelor Civil Engineering students of the University of Cagliari.For the 2017 edition, as usual, it is thus clear that DCEE2017 continued successfully to pursue its primary objective of exploring what design means in the field of Civil and Environmental Engineering and discussing interdisciplinary design strategies/innovations/approaches in co-operation with Architecture, Urban Planning, Topography experts…and more! A great success for SGAMR then, given that the previous editions of the international DCEE event have been held with success in Rome (2016), Taiwan (2015), Lyngby (2014), Worcester (2013) and Dajeon (2011).Besides, parallel submissions to SGAMR are from independent submissions that wanted to share their outcomes with the international research community.
