CSi Bridge v21.2 Portable – The House of Portable

csi bridge 21 portable


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.

One Window, Many Views

CSiBridge offers a single user interface to perform: Modeling, Analysis, Design, Scheduling, Load Rating, and Reporting.


CSiBridge offers a selection of templates for quickly starting a new bridge model or structure. This is often a good starting point to creating a model as the template can be modified later.

Interactive Database Editing

Interactive database editing allows users to edit model data in a table view which simplifies the task of making changes to the model. Tables are easily exportable and importable from Microsoft Excel and Microsoft Access.

Bridge Object Model

The bridge object model is a comprehensive assemblage of components that make up the entire bridge model. The parametric model is managed through the bridge object model. This includes: the modeling of deck sections, diaphragms, bearings, restrainers, foundation springs, superstructure variation, abutments, bents, hinges, tendon layouts, and more.

Bridge Wizard

The Bridge Wizard is a powerful tool that guides users step-by-step through the creation of a complete bridge model with instructions at each step to ensure that all of the necessary components are defined in the model.

Layout Lines

Layout lines define the the highway layout of the bridge. They can be defined within CSiBridge using bearing and station notation, or they can be imported using a TransXML file. As layout lines are modified, the entire bridge structure and its parametric geometry is updated.

Superstructure Deck Sections

CSiBridge has a wide array of parametric deck sections including concrete box girders, precast I and U girders, steel boxes, and steel girder bridges. All deck sections are parametrically configurable for an accurate bridge deck section definition.


Diaphragms may be located at the supports and along the spans. Types include concrete, steel girder, and detailed steel cross-frames. These may be skewed and staggered. Interior cross frames for steel U-girders may also be specified.

Parametric Variations

CSiBridge allows variations for the entire bridge or just parts of the bridge alignment and slope, for both horizontal or vertical variations of the deck section. Defining variations parametrically significantly reduces the amount of time spent on the modeling process.


The solid element is an eight-node element for modeling three-dimensional structures and solids. It is based upon an isoparametric formulation that includes nine optional incompatible bending modes and is useful for modeling objects in which loading, boundary conditions, section properties, or reactions vary by thickness.


Users can create and apply hinge properties to perform pushover analyses in CSiBridge. Nonlinear material behavior in frame elements (beam/column/brace) can be modeled using fiber hinges. This approach represents the material in the cross section as discrete points, each following the exact stress-strain curves of the material. Mixed materials, such as reinforced concrete and complex shapes can be represented.
