Seismic Behavior of Steel-Fiber-Reinforced High-Strength Concrete Shear Wall with CFST Columns: Experimental Investigation

To improve the seismic behavior of shear walls, a new composite wall composed steel-fiber-reinforced high-strength concrete (SFRHC) web and two square concrete-filled steel tube (CFST) columns, namely with CFST is proposed in this paper. Therefore, main purpose paper to present an experimental investigation SFRHC columns. Pseudo-static tests were carried out on seven performance walls was studied quantified terms aspects energy consumption, ductility stiffness degradation. Furthermore, results indicated that adding fiber can effectively restrain crack propagation further help dissipation capacity delay degradation their lateral force. Moreover, columns obviously superior conventionally reinforced wall, load-bearing capacity, ductility, because confinement effect web. Finally, preliminary study demonstrated has good potential be used regions high risk.
