Ø Explain the progression of an advanced blast-resistant wall system from UCSD research to its current use in BRMs

Ø Discuss the live field testing which validated the BRM system for high level blast events

Ø Display the flexibility of the system to be configured with multiple modules to form a blast-resistant building as seen in a current project

Ø Vanadium-steel alloy studs Ø Custom header and footer connections Ø Advanced blast/ballistic wall panels

Ø Applied Research Associates - Pecos Research and Testing Center (PRTC)

Ø  9,000 lbs ANFO (~8,000 lbs TNT equivalent) charge at 150 ft

Ø  3 BRMs with internal and external pressure sensors and one steel ISO container

Ø  6 BRMs configured to form a single blast-resistant building Ø Delivered to oil refinery job site via trucks and set with crane

Ø Units connected together with heavy duty bolts and steel plate Ø Walls and floor accommodate inputs for electrical, plumbing,

HVAC, etc

Ø Modular construction approach allows for minimal on-site labor and less operational down time for the refinery

Ø  Building receives final exterior coatings as desired by client

Ø  An advanced blast-resistant wall system was developed through extensive research at UCSD

Ø  Wall components have been effectively integrated into a blast-resistant modular configuration (BRM) which can withstand high level blast events

Ø  The BRM system has been utilized to design larger blast-resistant buildings which can be constructed piecewise off site and delivered

Ø  Given the proven efficiency and adaptability of a design driven by UCSD research, it can be expected that BRM work with CEER to develop further technologies will be characterized by the same level of efficiency: •  RPG and mortar defense systems •  Tornado and hurricane resistance (FEMA 361) •  Vapor cloud explosions •  Addition of sensor arrays and communication suites
