SEISMIC RETROFIT OF NON-DUCTILE R/C FRAME COLUMNS

Inadequate shear strength of reinforced concrete columns is one of the major problems in older existing buildings. Brittle shear failures may dominate the behavior of columns with small height to depth ratios. This paper presents results of an experimental study on the use of rectangular steel jackets for seismic retrofit of reinforced concrete columns with inadequate shear strength. Six large scale columns with inadequate transverse reinforcement were tested under cyclic lateral loading. The unretrofitted columns showed an early dramatic failure. However, the columns strengthened with rectangular steel jackets exhibited higher strength, ductility and energy dissipation.
