Designing Glass Holes For Bearing: An Approach from First Principles Adapted for the Practising Structural Glass Engineer

Benjamin Fay

The process of engineering glass holes for bearing loads can be time consuming and difficult to visualize but is often critical in achieving design objectives.

This presentation presents a collection of information from a variety of sources for determining tensile stress and probability of failure along the inner rim of a hole in bearing for some of the most common practical loading situations. This information can help facilitate fast, accurate and intuitive design, and allow the practicing structural glass engineer to focus on application and creativity.

Discussion is also given to the effect of: 1)undersized/oversized hole/pin relationships, 2)bushing materials, 3)different schemes of bearing in laminated glass, and 4)application examples from completed projects.
