In reinforced concrete (RC) structures, the sudden failure of a corner column is more likely to cause severe progressive collapse due to the weak tie force from the surrounding elements. Therefore, some effective strengthening measures can be used to improve the progressive collapse behavior of the structures. In this paper the progressive collapse behaviors of the GFRP strengthened RC beam-slab substructures subject to a corner-column-removal scenario were studied. First, a quasi-static experiment method was adopted to test the progressive collapse behavior of the beam-slab substructures including control specimen and strengthened specimens. Two techniques using externally bonded GFRP laminates and near surface mounted (NSM) GFRP tendons were applied to strengthen the specimens. Then, finite element (FE) analysis on the progressive collapse behavior of the beam-slab substructures was also carried out by the software MSC.marc. The calculated results were found to be agreeable with the test results.
