| Abstrait: |
The use of Carbon Fiber Reinforced Polymer (CFRP) materials to repair and strengthen inadequate lap splices in square and rectangular reinforced concrete columns is presented. Four large scale columns (three square columns and one rectangular column) were tested to examine the effectiveness of the rehabilitation methods for improving lap splice behavior. The test results show that a combination of CFRP jackets and CFRP anchors effectively confined the lap splices of the columns. The tensile capacity of the longitudinal bars was developed and the deformation capacity of the columns was considerably improved. The strengthening methods of RC columns using CFRP may provide a solution for improving structures vulnerable to progressive failure. |
