Strengthening Archaic Concrete Systems
Presented By: Peter B. Larson P.E.
Evaluation and design of repairs and upgrades on structures that pre-date building codes or the standardization of material specifications present unique challenges to the structural engineer. Mr. Larson will discuss these challenges, testing methods that can be employed to unearth information that is not readily available, and design methods that can be used to improve structural performance.
Mr. Larson will tie this discussion to his work on an adaptive re-use of Dallas High School, also known as Crozier Tech. This structure was designed in 1906 and is listed in the National Register of Historic Places as part of the Dallas High School Historic District. It sat vacant for 20 years, falling into a state of disrepair, and was listed by Texas Preservation as one of Texas’ Most Endangered Places. The building structure included steel, cast-iron, multi-wythe masonry, wood, and concrete. The discussion will focus on strengthening of the concrete slabs.
Peter Larson graduated from Iowa State University with a Bachelor of Science degree in Civil Engineering in 1977 and has forty plus years of experience in design of building structures. He has been a member of SEAoT since 1987 and has served as an officer at both the local and state level, including being a past President of the state organization. He was awarded an Honorary Membership in 2009 and received the Wilbur C. Schoeller Award in 2012. He has been a member of design teams that were awarded a National Award of Excellence by ICRI for structural strengthening of the concrete frame at T. Boone Pickens Cancer Hospital, a National AIA Grand Project Team Award for design team / construction team coordination on Southfield Public Library, an AISC National Certificate of Recognition for the design of the steel framed, multi-story Bridge of Hope, and a Preservation Dallas Award for the restoration of the 1859 wood framed sanctuary at Wheatland United Methodist Church. He is a member of ACI Committees 440 on Fiber Reinforced Polymers, 440 F on External Reinforcing using FRP, and 224 on Cracking.
