Abstract (EN): An experimental cyclic campaign of RC hollow piers has being carried out in the Laboratory for Earthquake and Structural Engineering (LESE) of the Faculty of Engineering of University of Porto (FEUP), aiming to establish, among other purposes, a strategy to retrofit RC hollow piers subjected to horizontal cyclic actions with axial load. The retrofit techniques intend to increase the shear strength and the ductility capacity through the application of CFRP sheets. The main objective of this paper is to evaluate and calibrate the efficiency of several retrofit solutions. The design criteria for the piers retrofit solutions and the different strategies for the practical application are presented, namely, the CFRP sheets for shear retrofit and CFRP base strip, with or without steel bars applied inside the hollow box, for ductility improvement, being the different types of retrofit grouped out in order to understand the main benefits of each one. Results of the experimental campaign allow to discuss and conclude about the efficiency of each retrofit solution, explicitly regarding the improvement of the shear strength and the ductility capacity.
