AB - Based on the modified compression field theory, this paper considers the  inter-locking force between recycled concrete aggregates and their effective  grain sizes, and establishes a shear model to describe accurately the  actual force of recycled concrete beams with web reinforcement.  Mathematical formulas for calculation of the interlocking force are  deduced, and the shear capacity of the recycled concrete beams can be  estimated. The data of five test beams and 20 test beams in open literature  are in good agreement with the theoretical prediction, which proves that  this method can be used to calculate the ultimate shear capacity for  practical applications.
