Load Duration and Interlayer Thickness Effects on Laminated Glass

Abstract

As part of an ongoing laminated glass research program at the Glass Research and Testing Laboratory at Texas Tech University, full‐scale laminated glass laboratory specimens were tested under uniform lateral loads and simply supported boundary conditions. Effects due to varying interlayer thicknesses and long‐duration (one hour) loads were observed. Interlayer thickness effects on laminated glass unit structural response were not observed to be large. Interlayer thickness effects on corner stresses were less than 10%, while center deflections were separated by less than 4%. During long‐duration tests, lateral pressures of 0.2 psi (1.4 kPa) were applied to
