The aim is, therefore, to contribute for developing and calibration a procedure that enables the evaluation of the efficiency of the strengthening strategies, their possibilities and application. It was also an objective of this work to explore the possibility of use this techniques on the improvement of existing buildings performance.engBiaxial cyclic behaviourEnergy dissipationRC columnRC column retrofittingStiffness degradationconference paper10.7712/120115.3435.1619
