Modeling, analysis and design of bridge structures have been integrated into CSiBridge to create the ultimate in computerized engineering tools. The ease with which all of these tasks can be accomplished makes CSiBridge the most versatile and productive software program available on the market today.
Using CSiBridge, engineers can easily define complex bridge geometries, boundary conditions and load cases. The bridge models are defined parametrically, using terms that are familiar to bridge engineers such as layout lines, spans, bearings, abutments, bents, hinges and post-tensioning. The software creates spine, shell or solid object models that update automatically as the bridge definition parameters are changed.
CSiBridge v20 Enhancements
- The transverse position of vehicle lanes has been automated for influence-based moving load analysis using floating lane sets.
- The effect of reinforcing steel on the axial creep and shrinkage behavior of concrete in columns and walls is now included in the time dependent staged-construction analysis.
- A pure event-to-event option has been added for nonlinear static analysis.
- Bridge superstructure design checks for precast I-girder and precast U-girder bridges have been implemented according to the BS 5400 British code.
- Bridge superstructure design checks for concrete slab bridges have been implemented according to the AASHTO LRFD code.
- Bridge superstructure design and rating of steel I-girder bridges now considers local girder effects when the bridge object is updated as a spine model.
- Superstructure design of concrete box-girder bridges according to AASHTO LRFD now offers the Modified Compression Field Theory (MCFT) method, including torsion, for performing shear design according to AASHTO 188.8.131.52.2.
- An option has been added to control the limiting negative stiffness ratio for frame hinges.
- On-screen measuring tools for measuring length, area, and angles have been added.
