Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams
Initial analysis and experiments
In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state is normally associate ...
Flexural behaviour of post-tensioned glass beams
Experimental and analytical study of three beam typologies
The concept of post-tensioned glass beams builds on the concrete analogy of the reinforced glass beams. By additionally prestressing the reinforcement in a post-tensioned system, a compressive pre-stress is applied on the glass, enhancing the initial fracture resistance in ben ...
Post-tensioning of glass beams
Analytical determination of the allowable pre-load
The effectiveness of post-tensioning in enhancing the fracture resistance of glass beams depends on the level of compressive pre-stress introduced at the glass edge surface that will in service be exposed to tensile stresses induced by bending. Maximum pre-load that can be app ...
