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

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
