Episode 111 - Can Glass Really Be Structural?

In this episode, we dig into structural glass design and explore why glass in buildings can be far more than a transparent enclosure. We talk through how engineers approach glass as a true structural material in systems where stiffness, redundancy, detailing, and post-breakage behavior can be just as important as ultimate strength.

We break down how engineers think about glass in tension, compression, and bending, how laminated assemblies and interlayers improve resilience, and why connections often control the performance of the entire system. The conversation also covers the differences between annealed, heat-strengthened, and fully tempered glass, how standards and testing inform design, common misconceptions about brittleness and safety, and why close collaboration between architects, fabricators, and engineers is essential when ambitious transparent structures are the goal.
