Traditionally, glass is widely used in buildings as windows where its brittleness and strength capacity are not significant. Although there is more demand for usage of glass as a structural material, common fear of its brittle nature has mostly hindered its structural use. Aesthetics, recyclability, and transparency are the main reasons of the interest for glass in structural field. Moreover, glass shows significantly more benefits for certain types of projects such as existing building extensions and historic building preservation, where envelopments with minimal visual interruption are needed. However, more research should be done to be able to meet the demands and benefit from the advantages of glass. This thesis aims to enhance the use of glass as a structural material, so a T-shaped glass beam is studied to develop a proper and safe design. Since glass is a brittle material and has high compressive strength and lower tensile strength, a T-beam is post-tensioned in order to increase its initial fracture capacity and obtain ductile post-fracture performance. In this study, several material tests are conducted to confirm the theoretical mechanical properties of glass as a material under compression and bending (indirect tension). After obtaining mechanical properties of the glass to be used in research, Finite Element Models (FEMs) of the T-beams were generated and analytical hand calculations were done for the same types of glass beams. The tests of T-shaped annealed (float) and tempered (toughened) glass beams with and without post-tensioning were conducted. The results of the experiments were compared with the analytical hand calculations and FEMs. Excel based computation sheets for design process and tables for quick and simple guide were also generated within the scope of this study.M.S. - Master of Scienc
