This paper aims to investigate the effect of retrofitting piers with CFRP on seismic damage in skew reinforced concrete bridges. To this end, damage limit states of bridge piers in terms of drift ratio are used. Finite element models of a whole bridge are developed for skew angles of 00, 100, 200and 300 and nonlinear time history analysis of the bridges with/without CFRP is performed, using a series of selected ground motion records. Compressive and tensile damage of concrete and drift ratio of bridge piers are estimated, and the results are compared with five damage limit states to specify bridge damage levels under seismic loads. The results show that CFRP strips decrease the compressive damage, the tensile damage, and drift ratio of bridge piers. Moreover, retrofitting piers with CFRP decreases the level of seismic damage of bridge piers. |
