Ten reinforced-concrete continuous deep beams with openings were tested to failure. The main variables investigated
were the shear span-to-overall depth ratio, and the size and location of openings. Two failure modes
influenced by the size and location of web openings regardless of the shear span-to-overall depth ratio were
observed. The normalised load capacity of beams having a web opening area ratio of 0.025 within exterior shear
spans was approximately similar to that of their companion solid beams. Continuous deep beams having web
openings within interior shear spans exhibited a higher load capacity reduction with the increase of the opening
size, similar to simply supported deep beams with web openings. Formulae based on the upper bound analysis of
the plasticity theory were proposed to predict the load capacity of continuous deep beams with web openings.
Comparisons between the measured and predicted load capacities showed a good agreement.
