This report details experiments conducted on beam-column subassemblages to determine their seismic behavior and evaluates the significance of the analytical and experimental results obtained. Two virgin concrete subassemblages and one repaired subassemblage were tested. A horizontal force was applied to one subassemblage to generate a large single hystersis loop, the initial part of which provided information on monotonic loading. Once the loading sequence was completed, the specimen was repaired by epoxy injection processes and an incremental cyclic load was applied until failure occurred. The second specimen was tested to failure by applying a loading sequence similar to the sequence applied to the repaired subassemblage.
