The main purpose of this work it to present an experimental campaign of different strengthening strategies
of RC columns, and evaluating benefits concerning their structural behavior for cyclic loading. 9 RC
columns were tested, two of them without strengthening and seven composed by strengthened columns
by CFRP or steel plates jacketing. 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 using this techniques on the
improvement of existing buildings performance.
