The foundation of any bridge in CSI Bridge is the . This defines the stationing, horizontal curves, and vertical grades. You can import these coordinates from Excel or LandXML files to ensure accuracy with civil site plans. Step B: Define Deck Sections
Bridges are built in phases, and stresses accumulate as the structure changes. Staged construction allows you to: Add or remove structural elements over a time scale. Apply loads at specific construction milestones. csi bridge user manual
The manual is organized for bridge-specific modeling, analysis, and design:
Detailed shell elements mapping the top slab, webs, and bottom slab. | Task | Manual Section | |------|----------------| |
Model construction and data entry = User Manual. Mathematical validation and solver settings = Analysis Reference.
View interactive graphical output showing demand-to-capacity (D/C) ratios along the bridge spans. Bridge Load Rating Step B: Define Deck Sections Bridges are built
Run a mesh convergence study. A finer mesh yields more accurate results but increases calculation times.
Before shaping the bridge, you must define what it is made of: Go to the tab.
Enter station coordinates, curves, and grades to match your highway alignment. Step 2: Bridge Deck Sections
Check the analysis log for any "Negative Stiffness" or "Numerical Instability" warnings, which typically point to unconstrained joints or missing boundary springs. Reviewing Results Use the tab to verify structural behavior:
