Austin, Texas


This year’s Structural Engineers Association of Texas (SEAoT) conference will be held in Austin, Texas, October 20-21, 2016. Traveling the short distance up the road from our San Antonio office, PEC Project Engineer, Marlon Bazan, Ph.D., P.E., will be giving a presentation on the Blast Design of Cold-Formed Steel Roof Trusses. Marlon has completed several blast design projects of cold-formed steel roof trusses for Department of Defense facilities during the last couple of years. Marlon regularly manages blast design projects for federal and military facilities, as well as industrial and petrochemical facilities. In addition to design, he also supports research projects and the development of design tools and criteria for blast-resistant design of buildings.

Look for Marlon at SEAoT as he presents Blast Design of Cold-Formed Steel Roof Trusses.

“Cold formed steel (CFS) roof trusses are a commonly used structural roof system in conventionally constructed buildings because of their architectural versatility, low cost and wide range of possible spans. These systems are increasingly becoming a roof system of choice in the Department of Defense (DoD) billeting and other types of facilities that are required to be designed for blast loading. Due to changes in the latest edition of the UFC 4-010-01, “DoD Minimum Antiterrorism Standards for Buildings”, blast design requirements can no longer be satisfied by simply providing enough standoff distance to potential VBIED (vehicle-borne improvised explosive device) locations. Based on the current UFC 4-010-01 standards, the adequacy of this type of roof system must be demonstrated through blast analysis or testing against the applicable blast load. This presents challenges in the blast design of these systems because of a lack in existing design guidance and response criteria. This presentation will provide an overview of the different issues and limitations of two analysis approaches that must be considered in the blast design of CFS roof trusses. The presentation will also illustrate critical aspects of the blast resistant analysis process using a real case study.”
