Dynamic analysis of reinforced concrete frames including joint shear deformation

The rehabilitation of existing buildings requires an assessment of their lateral load resisting capacity which may be limited by the strength and ductility capacity of their critical regions. From this assessment, a rehabilitation strategy can be formulated. Lack of adequate confinement and shear reinforcement in the beam–column joints of existing reinforced concrete frames may be the cause of brittle failure during a seismic event. Most of the …
