YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing\udtests on deep beams have focused on simply supported beams with a scaled depth below 600 mm. In the present\udpaper, test results of 12 two-span reinforced concrete deep beams are reported. The main parameters investigated\udwere the beam depth, which is varied from 400 mm to 720 mm, concrete compressive strength and shear span-tooverall\uddepth ratio. All beams had the same longitudinal top and bottom reinforcement and no web reinforcement to\udassess the effect of changing the beam depth on the shear strength of such beams. All beams tested failed owing to\uda significant diagonal crack connecting the edges of the load and intermediate support plates. The influence of\udbeam depth on shear strength was more pronounced on continuous deep beams than simple ones and on beams\udhaving higher concrete compressive strength. A numerical technique based on the upper bound analysis of the\udplasticity theory was developed to assess the load capacity of continuous deep beams. The influence of the beam\uddepth was covered by the effectiveness factor of concrete in compression to cater for size effect. Comparisons\udbetween the total capacity from the proposed technique and that experimentally measured in the current investigation\udand elsewhere show good agreement, even though the section depth of beams is varied
