| Abstract: | Stiffness and strength are key indexes to evaluate steel structure safety. With 3D finite element software ALGOR, metal structure of a gantry crane on the dam crest is simulated and calculated. According to requirements of the main girder stiffness and metal structure strength in related standards, the method is expounded of how to check the stiffness and strength of metal structure of gantry crane with the simulation results. |
