Abstract

An experimental investigation was conducted to study the failure mode of existing reinforcod concrete columns designed during the 1960s. The effectiveness of using corrugated steel jackets for enhancing the seismic flexural strength and ductility of these types of columns was examined. Three large-scale columns were tested under cyclic loading. The three columns represent existing column, current codedetailed column and rehabilitated coSurnn. The variables in the test specimens include the amount of column transverse re inforcement and jafketing of the column. The corrugated jacket was found to be effective in the rehabilitation of the selected existing structure, wbich does not meet the current seismic code requirements. A method is propd for the design of the corrugated steel jacket to enhance the lap splice capacity and ductility of the column.
