1. Problem definition

verification-ssll14

  • Material properties:

    • Young's modulus, E = 210 GPa
    • Poisson ratio, nu = 0.3

  • Section properties:

    • AB, DE:
      • Moment of inertia, Iy = 5.0E-4 m^4
    • BC, CD:
      • Moment of inertia, Iy = 2.5E-4 m^4

2. Songeya model

Load intensity for the distributed load is projected onto the axis of the member.
