    Abstract:

    In order to improve the deformation capacity and damage tolerance of the reinforced concrete columns, six reinforced concrete column specimens with fiber reinforced concrete (FRC) in the bottom region instead of ordinary concrete were tested under reversed cyclic lateral loading. The specimens’ shear span ratio is three and its configuration of stirrups are relatively few. The test results show that these columns exhibit shear failures after the longitudinal reinforcement yielding, and they have better deformation capacity and damage tolerance. The column with FRC in the bottom region can reduce the amount of constraint stirrup and shear stirrup. According to the test results, bending bearing capacity calculation method considering FRC tension action and shear capacity formula were established. The shear capacity calculated by the adopted formula are in good agreement with the test results.
