LIcensed-Hawaii_Bridge-MIDASoft

 

Summary of Session

The presentation gave a brief introduction to the bridge replacement and the design basis for the replacement. It will also cover the rational for the different models used in the analysis and the various features that MIDAS Civil offers that helps aid the designer in both modeling a bridge as well as extracting useful information from the analysis. Several of the models will be compared with one another to see how well different behaviors are captured under different loading conditions.

Project Information
Umauma Stream Bridge
- Replacement of historic steel girder trestle bridge on the Big Island of Hawaii.
- Steel plate girder bridge to replace riveted steel plate girder bridge from 1910.
