Purpose of the Webinar
• Vessel Collision Forces on Substructure Bents
- Utilize superstructure & adjacent bent stiffness
- Controlling case for river bents
• Soil Interaction with Drilled Shafts and Scour Effects
- Non-linear soil springs & torsional soil springs
- Four scour cases considered per project requirement
• Settlement Analysis
- Uniform & differential settlement effects on existing bridge due to fill for new bridge
• MIDAS vs. MDX
- Overall resultant moment comparison & exterior girder deflection comparison
Presentation Outline

• Bridge Layout and Typical Sections
- Steel plate girder & pre-stressed concrete girder units with two column bents
• Bridge Design Considerations
- Vessel collision, scour, settlement analysis
• Bridge Construction
- Levee districts & railroad coordination
