Abstract: This study investigates the effect of the volume fraction of steel fibers on the axial load response of 200 MPa ultrahigh-strength concrete (UHSC) columns. Behavioral aspects investigated include strength, ductility, and ...

Abstract: Twelve ultrahigh-strength concrete (UHSC) columns confined by rectangular hoops and crossties were constructed and tested under pure axial load. Primary variables of the investigation were the amount, spacing, and configuration ...
