Experimental and numerical analysis on the cyclic behavior of bridge piers with and without CFRP retrofit
Abstract
The main objective of this paper is to evaluate the cyclic behavior of RC hollow piers, with and without with CFRP retrofit, by comparison of experimental tests results with structural numerical modeling. The retrofit techniques aim to increase the shear strength and the ductility capacity through the establishment of principles and strategies applied in an experimental cyclic campaign of RC hollow piers, carried out in the Laboratory for Earthquake and Structural Engineering (LESE) of the Faculty of Engineering of University of Porto (FEUP). The evaluation and calibration of the efficiency of several retrofit solutions is also performed. The numerical simulations are carried out using two different methodologies: (i) fiber model and (ii) damage model. The fiber models based in a finite element discretiztion with non-linear behavior distributed along the elements length and cross-sectional area, while the damage model is supported on refined finite element (FE) meshes, with high complexity and detail levels in the constitutive laws defined for both concrete and steel. The concrete is simulated with a continuum damage model where several applications for bridges with hollow section piers can be found at Faria et al. [1]. Results of the experimental campaign allow to discuss and conclude about the efficiency of each numerical method, namely regarding the shear strength and the ductility capacity assessment.
