摘　　要：基于strut-and-tie模型理论,采用美国《混凝土结构设计规范》(ACI 318-11)对一开洞深梁进行了设计,并与采用我国《混凝土结构设计规范》(GB 50010—2010)的计算结果做了对比分析。在应用美国规范时采用MIDAS软件分析得到深梁的应力云图,并以此作为设计strut-and-tie模型的依据。最后对两种计算结果进行了分析比较。This paper was based on the theory of strut-and-tie model to design a deep beam which has the hole by using the American concrete structure design code （ACI 318-11 ） . And it was compared with the result of design by using the Chinese concrete structure design code （GB 50010-2010）. When using American code, the software MIDAS was used to analyze the stress nephogram and the stress nephogram was the basis of the strut-and-tie model. Finally, it compared these two calculation results.
