Abstract:
A steel-fiber reinforced polymer (FRP) composite material reinforced concrete column comprises an inner steel pipe arranged in the center, wherein the inner steel pipe is internally provided with an unbonded steel strand; the outside of the inner steel pipe is provided with an outer steel pipe, concrete is poured between the inner steel pipe and the outer steel pipe, a plurality of additional small steel pipes are evenly arranged outside the outer steel pipe, and each of the additional small steel pipes is internally provided with an additional unbonded steel strand. A composite bar cage coaxial with the outer steel pipe and arranged on the outside thereof is also provided, wherein both the outer steel pipe and the composite bar cage are covered by high-ductility concrete, and at a core area, the outside of the high-ductility concrete is wrapped with an anti-spalling layer.

Claim (Index 7):
A post-earthquake repair method for the steel-FRP composite material reinforced concrete column according to  claim 1 , comprising the following steps of:\n S1: stretching and drawing the additional unbonded steel strands in each of the additional small steel pipes and the unbonded steel strand in the inner steel pipe to enable the combined column to recover to a displacement status before earthquake; S2: eliminating damaged concrete in the core area of the concrete combined column until the outer steel pipe is exposed, using a steel plate to cover the outside of the outer steel pipe, welding the upper end of the steel plate with the outer steel pipe, and putting the lower end deep into a column platform for anchorage; S3: implanting a new steel-FRP composite bar or a stainless steel bar in a damaged area if the FRP of the SFCB is damaged, connecting the upper end to the original SFCB by means of mechanical anchorage and bonded anchorage in a combined manner, implanting the lower end with a bonded sleeve into a column platform anchorage area, arranging a pier head anchor at the end part of the stainless steel bar if the stainless steel bar is implanted, and grouting for anchorage; S4: confining the steel-FRP bar/stainless steel bar implanted in the core area by a steel wire rope; S5: pouring high-ductility concrete in the core area; and S6: wrapping FRP outside the high-ductility concrete poured in the core area in step S5, wherein the wrapping scope is larger than the scope of the high-ductility concrete poured to guarantee that the upper anchorage area of the newly implanted steel-FRP bar/stainless steel bar is in the bonded scope, and then finishing the repair.
