Abstract

Abstract

A total of eight specimens with slenderness ratio of 20.4 were tested to investigate the performance of eccentrically loaded square reinforced concrete (RC) columns. These eight columns included four unstrengthened columns, and four columns strengthened by FRP jackets. The main parameter varied in the tests was the load eccentricity. The experimental results demonstrated that the bearing capacities can not be enhanced effectively, but the ductility can be improved to some extent,especially for specimens with small eccentricities. If there is a need to enhance both bearing capacity and ductility of square RC long column, it is recommended that bi-directional FRP sheets should be used, or some other effective measures should be taken.
- FRP composites,
- confined concrete,
- reinforced concrete,
- square columns,
- bearing capacity,
- ductility
