Abstract EN
The factory-produced steel-fiber reinforced polymer composite bar (SFCB) is a new kind of reinforcement for concrete structures.
The manufacturing technology of SFCB is presented based on a large number of handmade specimens.
The calculated stress-strain curves of ordinary steel bar and SFCB under repeated tensile loading agree well with the corresponding experimental results.
The energy-dissipation capacity and residual strain of both steel bar and SFCB were analyzed.
Based on the good simulation results of ordinary steel bar and FRP bar under compressive loading, the compressive behavior of SFCB under monotonic loading was studied using the principle of equivalent flexural rigidity.
There are three failure modes of SFCB under compressive loading: elastic buckling, postyield buckling, and no buckling (ultimate compressive strength is reached).
The increase in the postyield stiffness of SFCB r s f can delay the postyield buckling of SFCB with a large length-to-diameter ratio, and an empirical equation for the relationship between the postbuckling stress and r s f is suggested, which can be used for the design of concrete structures reinforced by SFCB to consider the effect of reinforcement buckling.
