Seismic evaluation of masonry-infilled RC frames strengthen with shotcrete

فاقد چكيده فارسي

Masonry-infilled RC frames have been used in buildings for architectural and structural purposes. For Seismic behavior improvement, assessment of masonry-infilled frames is necessary. Masonry-infilled RC frames is such a usual structural method that if these frames been designed adequate would improve seismic performance of structure. In this article seismic behavior of masonry-infilled RC frames subjected to push-over analysis has been assessed by using ABAQUS. After verification , RC frame with masonry infill has been modeled and has been strengthened with shotcrete. The result of two cases has been compared and show that the strengthened ones are better in strength and stiffness and ductility.
