Title: Experimental cyclic tests and retrofit of RC hollow piers
Issue Date: 2006
Abstract: The main purpose of this paper is to present an experimental campaign of reinforced concretehollow section piers with different cross sections under cyclic loading, comparing the obtainedresults with those obtained for the same piers after seismic retrofitting, and evaluating benefitsconcerning their structural behaviour. The setup of the RC pier experimental tests was designed tocarry out cyclic horizontal top displacements with axial load using two orthogonal actuators with asliding device to allow pier top displacements and rotations, in spite of the vertical actuator beingfixed to a steel portal frame. Representative of typical bridge construction, square and rectangularhollow section RC piers were tested at LESE the Laboratory of Earthquake and StructuralEngineering at Faculty of Engineering of University of Porto. The structural behaviour and safetyimprovement of these piers are presented, with the retrofit techniques adopted, as well as theillustration of the external and internal damage pattern. The framework of this study is, therefore,to develop and calibrate procedures enabling the evaluation of the different retrofit solutionefficiency, their possibilities and fields of application.
