Optimizing the design of steel bridges using the principle of virtual work
Abstract eng: The Virtual Work Optimization Method (VWOM) is used in this paper to optimize a steel bridge. The VWOM is an automated method that minimizes the mass of a structure with a prescribed geometry, deflection criteria and load cases, while adhering to design code requirements. Members are selected from a user defined database to meet design constraints including stiffness and strength criteria. The rotational stiffness of connections can be specified and varied. The method is explained using a single span plate girder as an example. The Komati River Bridge is optimized as a case study. Results are compared to the mass of the existing bridge.
