YesTwelve reinforced-concrete continuous deep beams\ud having web openings within interior shear spans were\ud tested to failure. The main variables investigated were\ud the opening size and the amount of inclined\ud reinforcement around openings. An effective inclined\ud reinforcement factor combining the influence of the\ud amount of inclined web reinforcement and opening size\ud is proposed and used to analyse the structural behaviour\ud of continuous deep beams tested. It was observed that\ud the end support reaction, diagonal crack width and load\ud capacity of beams tested were significantly dependent on\ud the proposed effective inclined reinforcement factor. As\ud this factor increased, the end support reaction and\ud increasing rate of diagonal crack width were closer to\ud those of companion solid deep beams. In addition, a\ud higher load capacity was exhibited by beams having an\ud effective inclined reinforcement factor above 0.077 than\ud the companion solid deep beam. A numerical procedure\ud based on the upper-bound analysis of the plasticity\ud theory was proposed to estimate the load capacity of\ud beams tested. Comparisons between the measured and\ud predicted load capacities showed good agreement
