Monolithic Coefficient Values for Design when Seismically Strengthening RC Columns with Jackets
Monolithic coefficients correlate the behavior of strengthened reinforced concrete columns to that of respective monolithic columns and can be used to estimate strengthened column response. Finite element analyses are performed with different values of normalized axial load, jacket thickness, and jacket concrete strength. Four- and three-sided jackets are examined. Monolithic coefficients for strength, stiffness, and displacement at yield and failure are obtained by comparing results of strengthened and monolithic specimens. Calculated values are compared to existing code values and useful conclusions and practical guidance concerning the effect of the examined parameters on monolithic coefficient values are presented.
