xsection

xsection is a Python package designed to streamline engineering tasks involving structural cross sections. Features include:

• Automatic generation of fiber input data for simulations with FEDEASLab, xara, and OpenSees.
• Calculation of section properties including:
  • Timoshenko shear correction factors
  • Saint Venant and Vlasov torsion constants
  • Moment-Curvature realtions backed by the complete Xara/OpenSees material libraries.
  • Interaction surfaces
• Standard shape library including the complete AISC steel database and standard AASHTO-PCI-ASBI bridge box girders.
