Collaborating to Deliver a New Seismic Risk Rating System for the General Services Administration

Protection Engineering Consultants (PEC) recently collaborated with Rutherford + Chekene (R+C)—a structural, geotechnical, and building systems engineering firm headquartered in San Francisco, CA, and our partner on our current GSA IDIQ task …

Case Study

Sandy Soil Material Development for Landmine Modeling

As part of the United States Marine Corps (USMC) Mitigation of Blast Injuries through Modeling and Simulation project, Protection Engineering Consultants developed a sandy soil modeling strategy for LS-DYNA that resulted in excellent agreement with experimental data. In developing this strategy, a traditional all-ALE approach and a less conventional all-SPH approach were evaluated, as well as hybrid formulation strategies including combinations of ALE fluid and explosive materials with FEM, DEM, or SPH soil.

Case Study

Blast Analysis and Design of Cold Formed Steel Roof Trusses

Cold-formed steel roof trusses are one of the most commonly used roof systems in current construction due to their light weight, long-span capabilities, design flexibility, and fast erection times. PEC has developed three analysis approaches for the design of CFS roof trusses that allow us to better work with our clients to develop a solution that meets their specific project design criteria and budget.
