Abstract

Local stability is an important parameter of bearing capacity of bridge crane structure. The calculation method for the local stability of the main beam is specified in detail in gb3811-2008, but the calculation formula needs to know the stress magnitude of the web edge of the main beam. The traditional calculation method is complicated and time-consuming, which generally requires 2-3 working days, and is not accurate. The finite element analysis can obtain the stress distribution cloud map of the structure, and the direct extraction of the stress value from the finite element analysis results for the local stability check of the main beam can be completed within half a working day, and the calculation accuracy is improved.
