CALCULATION OF SHEAR CAPACITY OF RECYCLED CONCRETE BEAMS WITH WEB REINFORCEMENT BASED ON MODIFIED COMPRESSION FIELD THEORY
ABSTRACT
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.
