Regrinding Tempered Glass Weakens Load-Bearing Capacity, Posing Safety Risks for Structural Glass Applications
The researchers investigated how regrinding tempered glass edges affects their strength for use in load-bearing structures. They found that regrinding tempered glass can weaken its load-bearing capacity, especially when the depth of regrinding is significant. The study showed that heat-strengthened glass is less affected by regrinding than fully tempered glass due to different stress conditions. By testing laminated glass beams made from both types of glass with and without regrinding, the researchers confirmed that regrinding can impact the load-bearing ability of these glass components. These findings provide insights for designing structural glass elements with high optical quality while maintaining their strength.
