Non-Destructive Evaluation and Load Rating of Prestressed Double-Tee Joists at the Harbor Baptist Church
Sponsor: Structural Innovations Engineering and Consulting, P.C.
(co-PI: Dr. Brett Tempest)
In order to assess potential structural vulnerabilities resulting from fire exposure to prestressed double-tee roof joists, the research team will employ a suite of non-destructive tests. Existing double-tee joists in the front of the church where fire damage was nominal provide a baseline for comparison to the joists in the region of interest. The non-destructive tests include:
- Impact-Echo Testing
- Input-Output Experimental Modal Analysis
- Windsor Probe
- Experimental Load Rating
