SEISMIC REHABILITATION OF CONCRETE BRIDGES: VERIFICATION USING IN-SITU TESTS AT SOUTH TEMPLE BRIDGE ON INTERSTATE 15. FINAL REPORT

The present report describes the test procedures and results of three in-situ full-scale tests carried out in Salt Lake City, Utah in 1998. The tests were carried out on the northbound lanes of the State Street Bridge at Interstate 15, in Salt Lake City. The first test was carried out on a three column bridge bent in the as-is condition (Bent #5), the second test was carried out on a bent which was seismically retrofitted with carbon fiber reinforced polymer (CFRP) composites (Bent #6), and the third test was carried out on Bent #5, after it was repaired with epoxy injection and a seismic rehabilitation with CFRP composites (Bent #5R). The report provides detailed information on the test setup, the loading scheme used to simulate seismic loads, a description of the condition of the as-is bridge bents, the design of the CFRP composite for seismic retrofit of the bridge bents, and an assessment of the performance of the three bridge bents. The seismic retrofit goal of increasing the displacement ductility of the bridge by a factor of two was achieved.
