Axial compression tests of RC columns confined by aramid fiber belt prestressing
ABSTRACT
The seismic retrofit technique ofaramid fiber belt with initial prestressing was proposed by Yamakawa et al. in 2001, and it was verified that the seismic performance of poor RC columns could be improved by the proposed method. However, the axial compression be-havior of RC columns confined by the proposed method has yet to be investigated. In this paper, axial compression tests of RC columns confined by this technique with active and passive con-finement were conducted, and the axial compression behavior was investigated thoroughly
