CSiBridge 2017 v19



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 2017 v19 Enhancement

Graphical User Interface
Several edit menu forms enhanced to allow them to remain open for repetitive use with an apply button.

Keyboard shortcut keys implemented within the menu interface, including customization of the shortcuts.

Hysteresis Models
New and enhanced hysteresis models for nonlinear materials, hinges, and links have been added.

PMM Hinges
A new parametric P-M2-M3 frame hinge has been implemented for use with performance-based design and other types of nonlinear analysis

Bridge Modeler
Girder-Only Section Cuts
Girder-only section cuts implemented for steel I-girder bridge sections to capture changes in girder sections, staggered diaphragms, and splice locations in individual girders. This also improves the design and rating of steel I-girder sections by better accounting for the controlling section within each panel.

Linked Model
A new action “Clear and Create Linked Model” added to the Action dropdown list in Update Bridge Structural Model form. Once selected, the previous program-generated linked model will be cleared (and cleaned) first and a new linked model created.

Energy Plots
Step-by-step energy plots available for nonlinear direct-integration time-history load cases and for nonlinear static/staged-construction load cases.

Nonlinear Hinges
Model frame nonlinear hinges as links, allowing for use of nonlinear modal time-history analysis (FNA) for faster analysis.
Size of the saved analysis results files is reduced for multi-step nonlinear static and nonlinear direct-integration time-history load cases.

Speed of creating analysis model from a bridge object improved for the operation that creates the bridge loads.

Section Designer
Import Geometry
Import geometry from a DXF file into Section Designer.
