Fill Materials

Many in-fill materials are used to improve ductility of concrete filled steel tube (CFST), due to meeting need for a change of seismic design perspective form the previous emphasis on structural strength to emphasis on structural ductility and energy absorption. Among the various in-fill materials, steel fiber is gaining attention in the CFST column. This paper investigates effect of volume fractions of steel fiber to concrete on the behavior of short steel fiber reinforced concrete filled steel tube columns under axial compression. The volume fractions of steel fiber to concrete are 0.6, 0.9 and 1.2%. The results indicate that steel fiber reinforced concrete filled steel tube columns appears to have a significant increasing trend in ductility, and have a slight increasing trend in load capacity with volume fraction of steel fiber to concrete increasing. The failure mode of the composite columns is similar with that of CFST.

Frp Confinement

In this study, the co-effects of steel fibers and FRP confinement on the concrete behavior under the axial compression load are investigated. Thus, the experimental tests were conducted on 18 steel fiber-reinforced concrete (SFRC) specimens confined by FRP. Moreover, 24 existing experimental test results of FRP-confined specimens tested under axial compression are gathered to compile a reliable database for developing a mathematical model. In the conducted experimental tests, the concrete strength was varied as 26 MPa and 32.5 MPa and the steel fiber content was varied as 0.0%, 1.5%, and 3%. The specimens were confined with one and two layers of glass fiber reinforced polymer (GFRP) sheet. The experimental test results show that simultaneously using the steel fibers and FRP confinement in concrete not only significantly increases the peak strength and ultimate strain of concrete but also solves the issue of sudden failure in the FRP-confined concrete. The simulations confirm that the results of the proposed model are in good agreement with those of experimental tests.
