Edit Cross Section

Good morning,
In grillage bridge analysis, the bridge is divided into a number of beam elements with modification of some cross section’s properties like moment of inertia IZ and Iy of cross section.

How I can change the cross-section properties like moment of inertia IZ and Iy of cross section if I define the cross section in Sofiplus 2018 (New standard section).

Thank you.

Hello,
the cross section values Iz and Iy cannot be modified manually by the user. The program AQUA calculates these values depending on the given cross section.
As I understood your information you have a bridge with changing cross sections along the axis.
Here it is recommend to interpolate cross sections. SOFiSTiK offer to variants for interpolations:

  • Interpolation between two defined cross sections
    The two initial cross sections have to defined with identical names of the cross section elements (e.g. identical names for the polygonal points, the defined reinforcements, the shear cuts).
  • Interpolation with a master cross section which has defined with variables along an axis – CABD concept which is recommended for bridge design

With kind regards
