This study investigates the applicability and reliability of the strut-and-tie modelling that is recommended by the ACI 318 Building Code (2002) for designing continuous deep beams with openings. Presented herein are experimental results of two full-scale continuous reinforced concrete deep beams with openings subjected to concentrated loads. Each specimen was designed using the ACI 318 (2002) provisions for strut-and-tie models. Both specimens were found to be able to carry loads greater than the factored design load. The failure mechanism of each specimen corresponds well with the designed strut-and-tie models. The experimental results thus illustrate the reliability and conservative nature of strut-and-tie modelling for designing continuous deep beams with openings.
