Absolutely. The documentation includes specific tutorials and chapters on "Curved Bridge" modeling, detailing how to define horizontal alignments with superelevation and skew.
If you are just getting started, open CSiBridge and navigate to to explore these manuals directly from your desktop.
Choose (recommended for typical box/I-girders to capture local bending) or Update as Frame Object (for quick global behavior checks). Click OK to generate the visual mesh. 5. Loading and Vehicle Live Loads
The CSiBridge user manual is not just a list of commands; it is a technical repository that merges finite element theory with bridge engineering practice. Whether you are verifying a composite steel girder against FHWA standards, scheduling the construction sequence of a segmental bridge, or performing a nonlinear pushover analysis, the documentation provides the logical path. By combining the written manuals (accessed via the menu) with the Bridge Wizard and the Watch & Learn video series, engineers can master the software's entire workflow—from initial layout line definition to final load rating. csi bridge user manual
⚠️ No public, free PDF is legally available; the manual is proprietary.
Select your bridge type (e.g., Concrete Box Girder, Steel I-Girder, Precast Concrete U-Girder, Flat Slab).
: Computers & Structures, Inc. (CSI) maintains a comprehensive Knowledge Base that hosts manuals for all their software, including CSiBridge. Absolutely
Use explicit naming conventions for materials, load patterns, and frame sections to keep complex models highly auditable.
For vehicle live loads, the manual details how CSiBridge utilizes influence lines and surfaces. Users define traffic lanes and vehicle types (e.g., HL-93, Eurocode vehicles). The software then moves these loads across the lanes to calculate the absolute maximum envelopes for shear, moment, and torsion. Staged Construction Analysis
: Details on the SAPfire Analysis Engine , covering static, dynamic, and staged construction analysis, as well as code-based design for various bridge types. 3. Supplemental Learning Resources Loading and Vehicle Live Loads The CSiBridge user
