Item Damage resulting from the Oklahoma City bomb(Texas Tech University, 1996-12) Swofford, Jason LEarly on the morning of April 19,1995, terrorists detonated a large amount of high explosives on NW 5th Street, just north of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma. A rental truck contained approximately 5000 pounds of ammonium nitrate and fuel oil. Several buildings surrounding ground zero suffered structural damage, and many buildings suffered severe window breakage. The explosion killed 168 people and injured more than 600 others in proximity and away from ground zero. Flying glass shards resulting from fractured windows caused the majority of the injuries. The bombing of the Alfred P. Murrah Federal Building marked the largest terrorist act experienced in the United States. This document reports on the damage to structures caused by the blast, and more specifically the performance of various window glass types and window constructions.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 Nonlinear stress analysis of insulating glass units(Texas Tech University, 1986-05) Chou, Gee DavidNot available
