Use for quick and easy generation of the deck model geometry and corresponding mesh, geometric, material, support and local coordinate data for slab-on-beam composite I-girder bridges.

Define girder sections

Define cross-sectional information for a composite girder and slab (without upstands) for all required locations on the structure. 



Visualise the section being built in real-time as slab, top flange, web, and bottom flange dimensional data is entered.

Once defined, the composite I-Girder sections are used to define Girders.

Define girders

Define positions along the nominal bridge centreline at which pre-defined or newly created slab and girder cross-sections apply for a girder.



The length(s) over which section assignments are made for girders either side of the control centreline is calculated by the bridge wizard.

 

Once defined, the girder components are used to define spans.



Define spans

Define the girders present in each span along with any bracing runs that occur between girders. Girders with offset slabs may be mirrored to create symmetrical arrangements.

Once defined, spans are used to define a bridge model as a whole.

Define supports

Define supports for the girders that are present in each span along with any bracing that occurs between girders at these supports. 

Skew can be defined uniquely for each support, and independently at that support for any defined support bracing. 



Once defined, the supports are used in the definition of the bridge model as a whole.

Define whole bridge

Define the type of bridge (straight or curved) to be generated along with a minimum mesh size.

Spans defining the bridge are selected (or defined) along with stating a length over which they apply. An option to reverse a span is also provided. Supports at the end of each span also need to be stated.



Once defined, the model can be automatically generated by the wizard.
