EXPERIMENTAL STUDY ON STATIC AND FATIGUE SHEARING BEHAVIOR BETWEEN STEEL AND CONCRETE WITH BONDING AND MECHANICAL ACTION

Abstract

It is important to clarify the stress transfer mechanism through the contact surface between steel and concrete, or by the shear connector in steel-concrete hybrid structures. In this paper, the effect of the bonding and frictional action between steel and concrete contact surface, and the mechanical action by the stud shear connector on the shear strength and shear transmission behavior of the contact surface under the bearing stress is investigated by conducting the push-out test. Furthermore, the fatigue strength of the contact surface between steel and concrete with the stud shear connector under the bearing stress is investigated by employing the same push-out test. As a result, the static and fatigue bonding behavior of the contact surface between steel and concrete with the stud shear connector is clarified experimentally.
