Structural Analysis & Retrofits

Explosion Response Analysis

BakerRisk performs explosive safety analysis for planned explosive operations using procedures outlined in the UFC 3-340-02, “Structures to Resist the Effects of Accidental Explosions,” accepted by the Department of Defense Explosive Safety Board (DDESB). BakerRisk employs a wide variety of analysis tools accepted by the DDESB, including onlinear dynamic Single-Degree-of-Freedom (SDOF) analysis, engineering models employing explosive effects curves in the 3-340-02, and finite element analysis (FEA) using LS-DYNA and DYNA-3D. BakerRisk performs quantity distance analysis associated with explosive operations from blast, fragments (primary and secondary), and building debris. Structural and building debris analyses ensure safety and protection of personnel, and prevention of detonation propagation.



Explosive Containment

BakerRisk employs a wide variety of analysis tools for the design and analysis of explosive containment facilities. The design tools range from nonlinear dynamic Single-Degree-of -freedom (SDOF) analysis, to engineering models, to sophisticated finite element analysis using LS-DYNA and DYNA-3D. The complexity of some explosive containment vessels require sophisticated modeling of structural components, the interaction between components, their connections, and complex response modes associated with severe blast.

Sympathetic Detonation Analysis

Evaluation of sympathetic detonation of acceptor explosives often involves structural analysis of building components shielding the donor explosive. If the structural configuration of the donor area is too complex to allow simplified analysis, finite element analysis can be employed to evaluate failure of structural components and potential impact of structural debris on acceptor explosives.
