文摘
Test results of eight continuous reinforced SCC deep beams and code comparisons are presented. All beams tested failed due to a major diagonal crack formed between load and interior support plates. The shear strength of the beams tested is mainly controlled by concrete compressive strength. For the shear span-to-depth ratio considered, vertical web reinforcement had more influence on shear capacity. The strut-and-tie model recommended by different design codes showed conservative results.
