Item Experimental behavior of structurally glazed insulating glass units(Texas Tech University, 1989-05) Bailey, James RobertStructural glazing has become a popular method for finishing building exteriors in recent years. Structural glazing is a system of bonding glass, stone, or other materials to the structural frame of a building using structural silicones. Twenty-five to 40 percent of all new commercial glazing is structural glazing. More complex structural glazing systems use insulating glass (IG) units with structural silicone applied to all sides. No mechanical fasteners exist to hold the IG units in place. This design poses several interesting problems for engineers. Researchers at Texas Tech University conducted tests on eight structurally glazed IG unit samples. The National Science Foundation and several members of industry sponsored the research. These eight structurally glazed IG unit samples underwent applied simulated wind pressures on one or both sides. Instruments measured changes in structural seal and IG seal shapes. This dissertation defines changes in structural seal and IG seal shapes as the samples deform under pressure. This dissertation also discusses the behavior of these eight structurally glazed IG unit samples.Item Strain measurements in monolithic and laminated glass(Texas Tech University, 2001-08) Mackay, Tyler NAs the uses of laminated glass (LG) become more prevalent, the need to better understand LG behavior increases. Due to the variation in shear transfer capability of the interlayer with temperature, the behavior of LG is poorly defined. LG behaves similarly to monolithic glass at room temperature, but behaves differently at elevated temperatures. The objective of the research presented herein is to gain insight into the behavior of LG subjected to uniform load as temperature varies from room temperature to 158°F (70°C). The research consisted of measuring flexural strains and center deflections at the full design load and one-half design load. Glass Research and Testing Laboratory (GRTL) staff, at Texas Tech University, tested one LG specimen and one monolithic glass specimen for each of five geometries. The data collected indicates, in general, that LG having a low flexibility ratio displays different behavior from monolithic glass at room temperature and above. This conclusion falls in line with aspects of ASTM E 1300 (2000), although the flexibility ratio at which the behavior deviations become significant may differ from 150.
