FSM Bridge Wizard - Model


Enter the material properties, configuration and staging information of a bridge.

FSM Bridge Wizard Model dialog box


Apply Tapered Section

Select whether or not to apply Tapered Section or Uniform Section. Based on the selected section type, the guide diagram and input parameters change.


Bridge Material

Define the material type of the bridge girder. Click the ....png to the right of the selection field to add or modify material data..  



Specify the spans consecutively.



Specify the radius in the case of a curved bridge.


Convex curvature bulging to the +ve direction of the Global Y-axis on Global X-Y plane


Concave curvature bulging to the -ve direction of the Global Y-axis on Global X-Y plane


Fixed Support

Location of the fixed support (If more than one fixed support exists, the general procedure is used to revise the Wizard-generated data)


Segment Division per Span

Number of elements per span


Tapered Section Length

Dimensions of the tapered sections

S1, S2

Referring to the guide diagram, enter the required dimensions of the tapered sections.


Curvature 1, 2 : Exp.

Orders of the an exponential function defining the variable section (1~2)


Cold Joint(S3)

Location of concrete construction joint in terms of a span ratio



Location of tendon anchorage from the construction joint. The distance applies symmetrically to the construction joint and represents the ends of the thickened webs.



Distance from the center of a pier to one end of the diaphragm. The distance applies symmetrically and defines the zone of thickened webs.


Stage duration

Duration of each construction stage (ex., Duration for constructing the bridge segment from the buttress to the construction joint in the above diagram).

NOTE.png It represents the time that takes to assemble, cast and cure the segment and dismantle the formwork.


Initial Member Age

for member (girder)

NOTE.png Specify the initial age, which is the maturity of concrete at the start of a construction stage (i.e., aging of concrete taken place in the immediately preceding stage). It represents the age of concrete when the elements become subjected to loads. The member age is used to reflect the compressive strength (modulus of elasticity), creep, shrinkage, tension loss in tendons, etc. The age is applied at the time of calculating the reaction due to the self-weight of concrete and at the time the reactions of the MSS girders are imposed.
