- Abstract
- This report examines in detail the structural mechanics behavior of thin, layered glass units under lateral pressure relative to the behavior of monolithic glass plates of equal glass thickness. The theoretical study of specific geometries of layered glass units and monolithic glass plates provides interesting insights into the relative behaviors of these plates under lateral pressures. This study shows that layered glass units do not always develop larger principle tensile stresses than those found in monolithic glass plates of the same geometry and nominal thickness. An important observation is that thin glass plates having the same a/t ratio have been exactly the same distribution of stresses, under the same lateral pressure. This observation holds truc for both layered glass units and monolithic glass plates. Another observation is that a strength factor of 0.6 as given in various building codes for laminated glass units may not be appropriate for many window geometries and design wind pressures.
