| Abstract: | Stability is of great importance in the design of steel beams for rush repairs. In the light of the structural characteristics of the new 32-m railway steel beams for rush repairs, factors influencing the integral stability of the medium-spanned railway steel beam are analyzed by means of the finite element method in the paper, the result of which shows that the stability of the medium-spanned railway steel girder is up to the requirements in stability of the Technical Specifications. |
| Keywords: | new-type railway steel beams for rush repairs integral stability finite element |
