Bridge Design – Load Combinations & Scour

• Extreme Event Full Barge: Degradation only

• Extreme Event Empty Barge: Degradation & half 100-year Scour

• Strength & Service: Degradation & 500-year Scour

• Stability Extreme Event: Scour to Bedrock

Bridge Design – Load Combinations & Scour

• Extreme Event Full Barge: Degradation only - Controls for River Bents

Midas Advantages

• Geometry updates for Design-Build

• Result graphics & tables

• Composite-Beam & Plate Elements

• Substructure Analysis – Global Model

–Utilize superstructure & adjacent bent

–Non-linear & Torsional soil springs

–Non-linear analysis

Midas – Lessons Learned

• Substructure – multiple design files

• Separate analysis:

– P-Delta

–Nonlinear
