Facilities constructed for the U.S. Department of Defense (DoD) must often must be designed for blast loads in accordance with anti-terrorism requirements stipulated in UFC 4-010-01. As cross-laminated timber (CLT) and other mass timber solutions continue making inroads in federal construction projects, demand for a design methodology complete with response limits for CLT construction exposed to blast loads has emerged. This presentation will provide a primer on general blast design requirements for DoD facilities and introduce a blast design methodology for CLT construction based on two years of testing research.

Mark Weaver is a Principal Engineer at Karagozian & Case, Inc. where he utilizes engineering and computational methods to analyze and design a wide variety of structural components to resist the effects of blast and impact loads. His experience includes the blast-resistant design of window, door, wall, and roof systems for both new and existing structures, and methods that range from single degree-of-freedom to high-fidelity physics-based dynamic analysis. Mark has also served as the Principal Engineer on several test programs demonstrating the ability of timber, concrete, and steel systems to resist airblast, gas pressure, and fragmentation loads. He is a licensed Professional Engineer (Civil) and Structural Engineer in the state of California.

Leonardo Torres is a Principal Engineer at Karagozian & Case, Inc. and has over seventeen years of experience in the analysis and design of structural and mechanical systems subjected to an assortment of static and dynamic loadings. His work at K&C is primarily focused on designing structures to resist blast and impact effects from both military-issued munitions and bare high explosives commonly used in terrorist attacks on civil infrastructure. Leonardo’s dozens of blast vulnerability assessments and blast-resistant designs of new and existing structures at facilities worldwide. He has also executed numerous component and structural system designs to support K&C’s blast and impact research efforts for development of products, software and technology. Leonardo is a licensed structural engineer in the state of California and holds a bachelor’s degree in Civil Engineering from the University of California at Berkeley.
