A strut-and-tie model (STM) is proposed for the shear carrying capacity of continuous RC deep beams. First, the mathematical formulation is given to fully describe the geometry, derivation of internal forces, evaluation of compressive and tensile stresses, and consideration of concrete tension softening. Second, validation studies for the modified STM are made for number of tested beams from the literature. Finally, a comparative study is presented between the results of proposed STM with the models of ECP code and the ACI code
