RESPONSES OF UNDERGROUND STRUCTURES SUBJECTED TO BLAST LOADING
<p>Terrorism against American citizens and assets is real and growing. The number and intensity of domestic and international terrorist events, along with the September 11, 2001, attacks, change the way Americans think and live. According to the Blue Ribbon Panel (BRP) on Bridge and Tunnel Security …

Response of thin circular plates to central blast loading
… thin circular metal plates subjected to central blast loading is investigated using the ABAQUS general purpose finite element code. The finite element code incorporates non-linear geometry and material effects as well as strain rate sensitivity. A material failure model is also incorporated. The …

The effect of blast loading on a guy cable
The blast loading on a structure is a function of the incident blast wave characteristics, that is, overpressure and dynamic pressure. But the most damaging effect to the guy cable from a nuclear explosion would be the dynamic pressure caused by the high winds which follow the chock front. This …

Glass curtain wall and anchorage system response under blast loading
Extreme events, such as blasts, pose a severe threat to a building's structural integrity. The building envelope serves as the primary defense against external explosions. Blast hazards continue to pose a threat to occupant safety. To address such problems, research and development of …

Blast loading of sandwich panels with thin-walled tube cores
… the response of a novel sandwich panel under blast loading is presented. Thin-walled tubar members have been used extensively as energy absorbers under impact conditions. The progressive folding mechanism induced by axial crushing of the tubes allows for efficient dissipation of kinetic …

Analysis and simulation of welded plates subjected to blast loading
At present bIast protection as well as other forms of anti-terrorism measures are a high priority for defence forces and humanit.ar:ia:n organisations. Armoured vehicle used in mine protection and navy ship hulls utilise welding during their fabrication. A weld is defined by British Standards [1], …

Dynamics and failure analysis of architectural glazing subjected to blast loading
… that the majority of nonfatal injuries from bomb blasts result from flying fragments from architectural glazing. Use of laminated glass, two soda lime glass plies are adhered to a polyvinyl butyral (PVB) interlayer, has the potential for limiting such hazards. Most of the work on laminated glazing …
