Abstract
"Terrorist bomb attacks and threats are on the rise all over the world. The glass structures of exterior window panels may become a debris hazard to building occupants when high explosives, for example, a terrorist vehicle bomb or body bomb, are detonated outside of a building. It is much more hazardous in body bomb case than in other types of terrorist attacks because the attack could happen in close proximity of the buildings. The dynamic response of glass structures subjected to small blast load at a short distance, however, has not fully understood. To address this issue, a 3-D, nonlinear, dynamic finite element model has been developed in this work to analyze the stress in a monolithic glass panel subjected to small blast load at a short distance. In this study, the small blast load at a short distance is modeled as a spherical blast wave. The effects of standoff distance, TNT charge weight, and overall thickness of glass panel on the dynamic response have also been investigated. To study the failure probability of the monolithic glass structure subjected to spherical blast load, two-parameter Weibull distribution based on the cumulative damage theory is adopted to describe the cumulative probability of the glass panel failure. The damage probability of the monolithic glass panel is then predicted. It was found that the maximum principal stress at the top surface is important and can not be neglected for the cases with small blast load at a short distance. The damage probability should be evaluated both at the bottom surface and top surface"--Abstract, page iii.
