Abstract:
In order to improve the design method of the reinforced concrete deep beams in Chinese Code for Design of Concrete Structures(GB 50010—2002), the strut-and-tie model method for D-region of reinforced concrete members in ACI 318M—05 was modified according to the design method of the current Chinese code, and the bearing capacity calculation of strut-and-tie model for reinforced concrete deep beams was proposed. The strut-and-tie model method and the bearing capacity calculation method in the current Chinese code were compared and analyzed based on the test data both at home and abroad, including 52 shear failure specimens and 29 flexural failure specimens. The result shows that the strut-and-tie model method gives better prediction than that of the current Chinese code method.
