摘要：In this paper, the bottom frame beam of container building is analyzed by finite element method, and compared with the experimental results, the accuracy of the model is verified to meet the needs of the analysis. On this basis, by changing the stiffening position of the upper flange, the height of the web, the load layout and the thickness of the wall, the variation of the stability bearing capacity of the bottom frame beam was studied, the control factors affecting the stability bearing capacity of the bottom frame beam were obtained, and the selection suggestions were given.
