Risk Based Building Upgrades
Building Explosion Risk Mitigation
- Provide cost-effective building design by managing risk rather than reducing consequence
- Maximize risk reduction vs. cost
- Manage Safety Resources and Schedule Planning
- Develop building drawings (30%, 60%, construction drawings)
- Estimate required building capacity using idealized building model (P-i curves/ Occupant Vulnerability) and QRA results
- Achieve efficient/inexpensive design by separating building into key components and assessing simultaneously
- Design roof and wall components using Single-Degree-of-Freedom (SDOF) dynamic analysis and applicable response criteria
- Construct building-specific P-i diagram
- Calculate risk
- Iterate to reduce risk and/or cost
- Building specific P-i diagram for new design with SBR/BIR values
- Existing vs. Upgraded P-i curves
- Sketches of identified structural upgrades, 30%, 60%, or final design packages
- Compare Multiple Design Options
- Risk vs. Cost
- Manage Risk – Reduce Risk To Building Occupants
- Prioritize Design Options Based on Risk vs. Cost
- Propose the most optimal solution – Acceptable Risk at minimum cost
Risk Based Approach to Blast Resistant Upgrades
Coupling the results of a Quantitative Risk Assessment (QRA) with the calculated blast resistance of a building, BakerRisk is able to design structural upgrades to meet a client specified risk criteria instead of a specific blast load.
Pressure-impulse curves representing the blast capacity of structural upgrade overlaid with blast loads resulting from a wide range of postulated scenarios.
Accounting for the frequency associated with each blast load, the risk associated with each level of building damage and the cumulative explosion risk can be calculated.
