Experimental Study on the Seismic Performance of Columns Reinforced by the CFRP Bar and Sheet
Source abstract
Abstract
To analyze the influence of CFRP (Carbon Fiber Reinforced Polymer) reinforcement ratio and CFRP sheet on the self-centering performances of concrete circular columns, five concrete circular columns were tested under the low-cyclic reversed load in this work. The five concrete circular columns included 1 RC (Reinforced Concrete) column, 2 CFRP bars reinforced concrete circular columns and 2 CFRP bars reinforced concrete circular columns with CFRP sheet strengthening partially. The hysteretic curves, skeleton curves, stiffness degradation, strength degradation, residual deformations, energy dissipation and ductility of the five circular columns were obtained and analyzed to verify the improvement of the seismic performances of the specimens reinforced with CFRP bars and CFRP sheets. At the same time, the reference opinions for practical applications of CFRP bars and CFRP sheets in structures can be provided. The test results showed that the bearing capacity and deformation capacities of the concrete circular columns reinforced with CFRP bars were 25.5% and 25% higher than that of the RC column, respectively. The deformation capacities, energy consumption capacities and deformation recovery capacities of CFRP bars reinforced concrete circular columns with CFRP sheet strengthening partially were 21.5%, 40% and 78.5% higher than that of the RC column, respectively.
