| Abstract: |
This paper describes advantages of incorporating local analysis models in a Global Analysis Model (GAM) as compared to a more traditional design approach. Time History Analyses introduce a problem for detailed local analyses of special structural elements as the influence from the super structure is dynamic time dependent and thus more traditional verification approaches are not feasible. Incorporating local models in the GAM requires special software capable of handling the complexity of exchanging integral parts of the combined model. The detailed design of the Izmit Bay Suspension Bridge is used as an example, and descriptions are given of the local models prepared during design as well as the used analysis software. |
