Abstract
The report summarizes current experimental work at Cornell University concerning lightly reinforced concrete structures. The report includes: (1) a brief summary of the full-scale experiments conducted on the behavior of lightly reinforced concrete building frame components subjected to reversing cyclic loads (simulated seismic effects); (2) description of experimental findings on a repaired interior joint; and (3) results of tests on two retrofitted frame joint regions. A total of 34 interior and exterior beam-column joints were tested to identify the different damage mechanisms and study the effect of critical details.
