Abstract:
Following previous studies, the authors describe an experimental study performed 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. A numerical study, subsequently conducted to further investigate this subject, is also presented. It has been concluded 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 obtain a monolithic behavior of the composite element.
