Structural deficiencies in flexural and shear strength, and in ductility capacity of reinforced concrete columns of Californian bridges have required the development of effective and economic retrofit solutions. The paper describes relevant research at the University of California San Diego, and presents design recommendations based on rather extensive test results.
