中文摘要：

为完善中国《混凝土结构设计规范》（GB50010-2002）中关于钢筋混凝土深梁的承载力设计方法，根据美国ACI318M—05规范D区拉-压杆模型方法，按中国规范的设计表达式，提出了钢筋混凝土深梁承载力的拉-压杆模型计算方法。基于所收集到的各国52个受剪破坏和29个受弯破坏的深梁试验数据，分别采用拉-压杆模型方法和中国GB50010-2002规范深梁承载力计算方法，对试验结果进行了对比分析。结果表明，拉-压杆模型方法的计算结果比中国GB50010-2002规范方法更准确。

英文摘要：

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.
