Abstract


  • A new method of reinforcing concrete columns with steel equal

    angle (SEA) sections has been investigated. A total of 12 square

    high-strength concrete (HSC) column specimens (with 210 mm

    [8.26 in.] sides and 600 mm [23.62 in.] height) reinforced longitudinally

    with either steel bars or SEA sections were cast and

    tested. The lateral tie spacing of specimens varied from 50 to

    400 mm (1.96 to 15.74 in.). The influences of the type of longitudinal

    reinforcement and the spacing of lateral ties on the behavior of

    HSC specimens under axial compression were investigated. Experimental

    results showed that the use of the SEA sections as longitudinal

    reinforcements in HSC column specimens led to significant

    improvements in the axial load-carrying capacity and ductility

    compared to the corresponding HSC column specimens reinforced

    longitudinally with steel bars.
