Reinforced Concrete Jacketing--Interface Influence on Cyclic Loading Response

This paper reports on experimental and numerical studies conducted to analyze the influence of the interface treatment on the seismic behavior of columns strengthened by reinforced concrete (RC) jacketing to increase their ultimate bending moment. Results show that for undamaged columns with a bending moment/shear force ratio greater than 1.0, it is not necessary to consider any type of interface treatment before casting a RC jacket with a thickness less than 17.5% of the column width to achieve a monolithic behavior of the composite element subjected to cyclic loading. This finding can result in significant money and time savings due to the elimination of unnecessary interface treatment.
