Blast Design
It's the unexpected that changes our lives. To expect the unexpected shows a thoroughly modern intellect.
Deliverables
1. Blast assessment summary report detailing the above work (design basis threats, performance criteria, structural blast assessment calculations, façade assessment calculations, design recommendations to improve blast resistance of the structure, alternative measures to improve blast resistance, and HVM requirements).
2. Mark up plans of mitigation measures
Exclusions
1. Close in detonation
2. Computational fluid dynamics calculations to calculate transient pressure-time histories incorporating pressure wave propagation around adjacent obstacles.
3. Non-linear FE analysis to determine the global response of the structure to collapse.
Qualifications of Blast consultant
1. 15+ years of experience as a Structural Engineer with a focus on the security and protection engineering field.
2. Developed algorithms for the calculation of blast pressures to support vulnerability assessments of mission-critical government buildings.
3. Used weapon effects software to develop structural components selection charts for the effect of indirect fire weapons.
4. Experience in regularly designing and managing physical security and blast-resistant designs (Design-build or Design-bid-build) efforts for numerous buildings for conformance with the DoD (United States Department of Defense) requirements in UFC 4-010-01, ISC Physical Security Criteria for Federal Facilities, and Physical Security Design Manual for mission-critical facilities.
5. Experience of managing and leading large test and research efforts for the Department of State (DoS) in the field of blast-resistant design and response of structures.
6. Extensive experience in performing progressive collapse analysis and design of buildings using both GSA and DoD standards, including assessments and retrofit designs for existing structures.
7. Experience of research in the development of dynamic and static increase factors for static analysis methods in the effort to update the UFC 4-023-03 “Design of Buildings to Resist Progressive Collapse”.
8. Experience in Containment Structures Design for Internal Blast and Fragmentations Blast and Shock Evaluation of equipment based on OBO (Overseas Building Operations) Embassy Standards
9. Experience in Complete frame response of steel buildings subjected to blast loads Counter-mobility barriers Blast Testing (Arena and Shock Tube) test plan development, instrumentation planning, post-test inspection, and evaluation of structures, data processing, and post-test analysis.
10. Education:- M.S. in Civil Engineering & B.S. in Engineering
Buildings, facilities, and sites that are susceptible to blast attacks require special studies in terms of blast resistant building designs.
Blast load calculations and building strength calculations including concrete and steel structure designs to resist ballast load, materials response and characteristics, CFRP (Carbon Fiber Reinforced Polymer) design principle to resist the building against blast loads, the integrity management system procedures, collapse analysis, etc., will help owners to take scientific and calculated calls on most economic ways to design blast resistant buildings.
Frontiertech can provide detailed blast study, blast result analysis & blast consultancy solutions
Scope of Service
1. Review the blast design criteria, site plans, and architectural plans to confirm the relevant design basis threats (charge weight and location) of critical areas based on performance criteria.
2. Review design information and relevant design standards
3. Workshop with design team members to understand design, constraints, and interfaces
4. Calculation of blast loads onto the structure.
5. Assess façade system including glazing build-up, fixings, and framing members.
6. Structural assessment of representative column, slab, and supporting beams.
7. Qualitative assessment of the structure to resist progressive collapse.
8. Based on the structural, façade and qualitative assessment, make recommendations to improve blast resilience of structure eg. section sizes, reinforcement arrangement, span lengths, etc.
9. Identify alternative or additional protective design systems and strategies that may be more cost-effective, improve blast resistance or mitigate debris (eg. materials, fittings, finishes, planning, procedural measures, physical security)
10. To determine suitable security barriers to maintain the stand-off distance used, carry out vehicle dynamics assessment to determine the vehicle impact speed, angle, and energy
11. Determine appropriate Hostile Vehicle Mitigation measures based on the above Vehicle Dynamics Assessment.
