Title: Load resistance of trapezoidal window glass
Author: Jackson, Ryan Crawford
Abstract: Virtually all glass used in aircraft control tower cabs have a trapezoidal geometry . Currently , the Federal Aviation Administration (FAA ) has no formal design methodology for trapezoidal window glass . The objective of the research presented herein consists of gaining insight into the behavior and load resistance of trapezoidal window glass . The research consisted of loading trapezoidal window glass specimens to fracture using a load that increased linearly with time , measuring the magnitude of loading at fracture and locating the fracture origin , and measuring the deflection of the window glass . Glass Research and Testing Laboratory (GRTL ) staff at Texas Tech University tested one sample comprised of 13 monolithic glass specimens removed from Insulating Glass (IG ) units and a second sample comprised of 8 Laminated Glass (LG )lites . Analyses of failure load data indicate that load resistance of the monolithic sample falls below values that current design methodology predicts . Even so , the experimental load resistance data are not significantly lower than other experimental load resistance data . Experimental load resistance data from the laminated glass sample falls in line with values predicted by current design methodologies .
