A
new seismic
retrofitting method for existing
reinforced concrete columns using
continuous fiber rope, CF rope,
coupled with concrete jacket is developed. CF
rope is enough flexible to be easily arranged in structural members by hand
and, apart from other FRP materials for concrete such as FRP rod, grid and
sheet, CF rope is applied without epoxy resin. This paper presents tests of
reinforced concrete column specimens retrofitted with CF rope. Aramid and
vinylon CF rope was wound continuously around the column periphery. Instead of
epoxy resin, concrete jacket was cast to bond CF rope with the original member
and to protect CF rope from environmental attacks. The column specimens were
tested under reversed cyclic load. It was experimentally verified that the
proposed
retrofitting method can successfully increase seismic resistance of
the member.
