Stress Finite Element Modeling Analysis of Simply Supported Beam Bridge

In order to quickly and accurately analyze the stress and strain of simply supported beam bridge, overcome the problems of insufficient lightweight of finite element analysis software, single analysis type and difficult expansion, a bridge stress and stress weakness analysis method based on finite element analysis is proposed. This method improves the analysis accuracy by independently designing the analysis program and using symbolic computation, and can optimize and supplement the existing analysis software according to the demand. The example verification shows that this method can effectively analyze the bridge stress, accurately analyze multiple stress weaknesses of the model, and display its position. The accuracy and speed of the analysis are considerable.
