Structure Type
Select the type of bridge.
2-Dimensional
2-Dimensional bridge
3-Dimensional
3-Dimensional bridge
Type of Bridge
Select a bridge type.
Normal Type Frame
Normal Type Frame is divided into Underground and Exposed types depending on the height of the overburden.
Pi Type Frame
Box Culvert
Box Culvert is divided into Underground and Exposed types depending on the height of overburden.
Material
Material property type.
Span
Specify the spans consecutively.
Skew Angle

Shape Variation of Top Slab
Select the option to model the tapered section of a haunch. If this option is not selected, the haunch is considered as a rigid zone using Beam End Offset.
Circle type
Select when the haunch is circularly varying.
Polynomial type
Select when the haunch variation is expressed as a polynomial function.
Number of Element
The number of elements within the haunch.
Division Ratio
Length ratios of the elements in the haunch
(Length of the elements of the haunch in the center/Length of the elements in the contiguous haunch to walls)
Curvature Exp
Order of a polynomial function
Size of Plate Element
Select the option to model the tapered section of a haunch. If this option is not selected, the haunch is considered as a rigid zone using Beam End Offset.
Wing Wall
Thickness
Thickness of wing wall.
Radius
Check in the box and specify the radius in the case of a curved bridge.
Convex
Convex curvature (center of circle located below).
Concave
Concave curvature (center of the circle located above).
Radiate Type
Spans and supports are laid out in a radial pattern.
Parallel Type
Support lines are laid out parallel to one another.
Radial Type becomes activated for a curved bridge. If "Convex" is selected, spans become shorter towards the center of the circle.
Dimensions
Referring to the guide diagram, enter the dimensions of the bridge.
