Strengthening Archaic Concrete Systems

Presented By:  Peter B. Larson P.E.

Abstract:  

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.
