Abstract：In recent years, great progresses have been made on the establishment of large-scale reinforced concrete (RC) structures. The increases on the size, span and height of the engineering structures and the diversification of the structural types, make the bearing capacity of the RC members larger and larger, and the mechanical system more and more complicated. The size effect of the RC members brings new challenges to the safe design on concrete structures (especially those large-scale RC concrete structures). In this study, the experiments and simulations of the failure mechanism and the size effect on the nominal shear/flexural strengths, compressive strengths and buckling strengths of the RC members (including beams, columns, and beam-column connections) are briefly reviewed. Moreover, some research areas needed to be strengthened and investigated are elaborated. Generally, subsequent research efforts shall be made on the size effect mechanism by experiments of large-scale RC members in conjunction with the simulation methods, so that a more reasonable theory of size effect can be established, and the design methodology of concrete structures can be optimized.
