Optimization Analysis and Verification of Negative Moment Reduction for Bridge Structure Based Different Support Pattern

Abstract:

Taking use of SolidWorks and ANSYS Workbench FEM software to establish numerical analysis model and using the node mapping and sectional integral method for the calculation of three-dimensional solid model of bending moment, this paper puts forward a negative moment optimal formula. The optimal formula including parameters λ when took into account the different supporting patterns for continuous box beam bridges. With the comparative analysis of CODE(JTG D62-2004) method and measured data, it draws a conclusion that considering the support patterns on pier top negative moment influence on engineering structural analysis is more appropriate.
