Repair and retrofit of reinforced concrete columns

Research output: Contribution to conferencePaperpeer-review


Inadequate shear strength, and inadequate flexural strength and ductility are two major deficiencies in non-ductile reinforced concrete columns constructed before 1970's. These deficiencies limit the lateral strength and ductility of older reinforced concrete moment resisting frames. This paper presents the use of steel jackets for strengthening columns with inadequate shear strength and inadequate lap splices in the longitudinal reinforcement. Unlike the basic unretrofitted columns, the retrofitted columns exhibited very good ductility and energy dissipation.
