Experimental and Analytical Study of External Reinforced Glass Beams
Abstract— Glass is used in buildings as partition wall, window panels, etc in the past centuries as a non structural element which do not carry loads other than its self weight. But it is used as structural element for the past few decades. Nowadays Glasses are used as beams in roofs of glass structures which bring light into the building and serves to eco - friendly world. Glass has very high compressive strength compared to other building materials but low tensile strength due to its surface flaws, also it is a brittle material. In order to increase the safety of structural glass in structures, glass has to be converted to ductile by providing reinforcement. In glass beams reinforcements are provided in the tensile zone in various forms to increase the flexural behavior. This work presents experimental and analytical study of glass beams with reinforcement provided by bonding stainless steel plate at the bottom reinforcements are provided in the tensile zone in various forms to increase the flexural behavior. This work presents experimental and analytical study of glass beams with reinforcement provided by bonding stainless steel plate at the bottom. Analytical study is done in ABAQUS finite element software where Quarter beam is modeled by taking the advantage of the symmetry of the boundary condition, loading condition, and cross section. Eight beams made up of polyvinyl butyl laminated glass of annealed and toughened type with three different thicknesses of stainless steel plates were analyzed. Results from Analytical simulation show good agreement with the experimental results. The analytical work performed in the ABAQUS software was verified by analyzing similar reinforced glass beams with the input values from the published literature.
