“…Consideration must be given to this aspect when RC piers with hollow sections are rehabilitated. Delgado et al (2012) undertook experimental cyclic shear failure tests and design procedures for the rehabilitation of square hollow piers using CFRP sheets along their entire height. Various transverse reinforcement detailing scenarios were assessed to determine their shear-failure efficiency.…”

“…Various columns with CFRP composite retrofits have been tested to obtain their cyclic performance. The factors that influence the performance of CFRPstrengthened RC columns have also been experimentally investigated, such as section sizes, aspect ratio, volumetric ratio of lateral steel, the level of axial load, fibre-reinforced polymer (FRP) jacket confinement stiffness and the area of FRP confining reinforcement (Delgado et al, 2012;Gu et al, 2010;Haroun and Elsanadedy, 2005;Iacobucci et al, 2003;Seible et al, 1997;Sheikh and Bayrak, 2001). In these aforementioned quasi-static tests, the column specimens were subjected to a predefined history of loads or displacements at a lower rate, and as a result, the cyclic responses of the columns are unable to accurately reflect the effectiveness of CFRP composite during an actual seismic event.…”

The behaviour of bridge columns strengthened using carbon fibre–reinforced polymer composites has been studied extensively. However, few investigations have been conducted regarding the influence of carbon fibre–reinforced polymer-strengthened columns on the seismic behaviour of reinforced concrete continuous girder bridges. This article details the hybrid simulations of a continuous reinforced concrete girder bridge whose columns are strengthened by carbon fibre–reinforced polymer jackets. In the hybrid simulations, one ductile column is selected as the experimental element, which is represented by a 1/2.5-scale specimen, and the remaining bridge parts are simultaneously modelled in OpenSees (the Open System for Earthquake Engineering Simulation). After combining the experimental element and the numerical substructure, the hybrid analysis model is developed with the established hybrid simulation system. The displacements of the bridge and the lateral force–displacement response of the experimental element in hybrid simulation are obtained. Compared with the results of numerical simulation, the stability and accuracy of the established hybrid simulation system are demonstrated. Meanwhile, the comparative hybrid simulation results of the as-built bridge and the carbon fibre–reinforced polymer-strengthened bridge also prove the effectiveness of the carbon fibre–reinforced polymer jackets’ confinement in the continuous reinforced concrete girder bridge.

“…This paper focus on the analysis of damages on hollow piers due to the seismic action, proposing a methodology to characterize the limit states of damage under the perspective of the physical behaviour. To establish a correspondence between physical damage states and structural parameters, a set of results of quasi-static experimental tests was analysed, in hollow piers of reinforced concrete subject to cyclic loading [1][2][3].…”
