Computers and Structures, Inc. (CSI), has released an updated (version 19.2.1) Bridge 2017, is specialized analysis and design software tailored for the engineering of bridge systems.
CSiBridge 2017 19.2.1 Enhancements:
Version 19.2.1 was released shortly after version 19.2.0 to address a few issues with the v19.2.0 release. For this reason, the Release Notes for version 19.2.0 are also included in this list.
Changes from version 19.2.0 (Released 2017-08-22)
202779 The version number has been changed to v19.2.1 for a new minor release. Models run in v19.2.0 can be opened in v19.2.1 and the results displayed without re-running analysis or design. Likewise, models run in v19.2.1 can be opened in v19.2.0 and results displayed without re-running analysis or design. No results have changed since v19.2.0.
202861 An incident was resolved where CSiBridge could terminate when creating a bridge object from a blank model and using the bridge wizard to gradually build up the bridge components and bridge object. Using the quick bridge template did not generate this problem.
202585 An incident was resolved in which the display of the analysis model did not show some area elements when area springs were present. This was a graphical issue only and did not affect results.
202643 An incident was resolved where an error message would be given when trying to display bridge object load assigns. This was a display issue only and did not affect results. This issue only affected v19.2.0.
202692 An incident was resolved in which analysis results (deformed shape, forces, moments, stresses) were not being displayed in the model windows for load cases that continued from, or used the stiffness of, a previous load case, unless that previous load case was a staged-construction load case. This was a display issue only. Results were not affected, and were still available in the database tables and plot functions. The display of results for load combinations was not affected. Design results were not affected. This error was present only in version 19.2.0.
201990 An incident was resolved in which an incomplete DXF file was exported for models where links were requested to be exported and there were more links than frames in the model. When there were fewer links than frames the DXF file was completed, but the link labels would have been drawn in the incorrect location.
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 design allows for quick and easy design and retrofitting of steel and concrete bridges. The parametric modeler allows the user to build simple or complex bridge models and to make changes efficiently while maintaining total control over the design process. Lanes and vehicles can be defined quickly and include width effects. Simple and practical Gantt charts are available to simulate modeling of construction sequences and scheduling.
