| Abstract: |
When using the 3D frame analytical method in bridges design as well as in structural soundness evaluation of existing bridges such as steel arches or steel trusses, as structural responses vary according to modeling methods of bridge members, their margins of safety should be differently evaluated. By examining the effect on analytical and final design results due to differences in modelling methods on a 3D frame analysis of a steel arch bridge, it is confirmed that the method of modelling without secondary members (considered as safe evaluation) does not result in safe evaluation for all primary members. |
