DYNAMIC ANALYSIS AND DESIGN OF BLAST-LOADED STRUCTURES
BAKER ENGINEERING AND RISK CONSULTANTS, INC. www.BakerRisk.com
Baker Engineering and Risk Consultants, Inc. (BakerRisk) has extensive experience in blast design and evaluation of protective structures. Applications have included the design of new blast resistant buildings, blast containment chambers, and structural upgrades to existing buildings for industry and government. We have developed a wide range of constructible engineering solutions for our clients by combining practical construction experience with research and development capabilities. Through our involvement in accident investigations, structural blast testing, and advanced analyses, we have gained a fundamental understanding of how buildings and structures respond under blast loading and their varying modes of failure.
Capabilities
• Analysis of conventional construction to evaluate performance under blast loads
• Upgrade of conventional construction to resist moderate blast loads for personnel and equipment protection
• Conceptual design of new facilities to determine optimal siting and construction requirements while meeting blast criteria
• New building blast resistant design
• Blast containment chambers for explosion testing, containment of processes involving explosion of flammable vapors or chemicals, and for disposal or transport of suspected subversive devices
• Upgrade of existing blast resistant buildings to enhance blast capacity
• Design of barricades to control fragments and suppress blast from potential explosions
• Support during construction to resolve issues which could affect blast hardened facilities and explosion safety
• Design of enclosures for high pressure pneumatic and hydraulic testing
• Counter-terrorist structural mitigation techniques for new and existing structures
