» COMBINED BENDING AND AXIAL LOAD STRENGTHENING WITH PLATES AND CARBON FIBRE FABRICS
- The pillar has deficiencies in longitudinal reinforcement and shear stirrups, and needs to achieve a higher compressive load-bearing capacity
- The longitudinal reinforcement may be supplemented by the use of pultruded carbon fibre plates, with fibres placed parallel to the axis of the pillar and properly anchored at the junctions by aramid connectors, while shear and compressive strength can be increased by wrapping the pillar with unidirectional fibres centre spaced or applied around the entire perimeter of the pillar.
