SEISMIC PERFORMANCE OF INTERIOR POST-TENSIONED CONCRETE WIDE BEAMS

This paper describes research in which an interior posttensioned concrete wide beam subassemblage was tested under quasistatic cyclic loading to determine its performance under lateral action. A special debonding strategy was implemented in the design of the subassemblage to improve the performance of the connection. The subassemblage was tested up to 3.5% drift ratio and was found to perform very well. Overall, the subassemblage was found to have low energy dissipation capacity, good displacement capacity, and small residual drift. The main issues studied in the test were formation and growth of cracks, behavior of the hysteretic response, and strain behavior of the specimen. Lastly, results from this investigation were compared with results from a prior investigation on a similar reinforced concrete subassemblage.
