Abstract:The secondary development of object-oriented language Python was used to calculate the axial force in a certain bridge structure with the application platforms of the famous Simulia Abaqus.Advantages of Abaqus scripting interface and objects logical structure in the development was discussed in this paper.Reliability analysis codes were also introduced to carry out bridge structural reliability analysis.Re-modularization of industrial simulation platform can highly reduce duplication of logic,make the process clear and concise and thus improve efficiency and reliability of bridge design.
