Abstract:The web openings of steel beams in a project are beyond limit of Chinese code. Finite element analysis was used to optimize the design of the steel beams with different reinforcement measures and an innovative reinforcement scheme was proposed. By conducting a series of parameter analysis on the basis of this scheme, the influence tendency of different measures on the mechanical properties of steel beams with web openings were ascertained by using the finite element software ABAQUS, and the last design proposal was provided.
Keywords:H\|shaped steel beam; web opening; finite element method; optimization design
