摘要：In order to analyze the effect of rebar size on the compressive strength of concrete cover, the axial behavior of a prism with a central rebar was experimentally and theoretically investigated. The test results indicated that the concrete compressive strength with rebar was relatively smaller than the axial compressive strength of prism that was similar with the concrete strength of cylinder. Further, the degree of reduction in the concrete compressive strength increased as the diameter-thickness ratio increased. Moreover, based on the test results and walled cylinder theory, the influence of rebar on the concrete compressive strength can be better understood. Lastly, in the structural design, the small rebar size and big concrete cover thickness should be chosen so that the effect of splitting action on concrete cover was weaken.
