Simplified Stress Analysis

  • Modeled the IsoTruss grid structure as a closed, multi-cell box beam.
    1. Longitudinal members
      • Resist all axial and bending loads.
      • Stresses calculated using beam theory.
    2. Helical members
      • Carry transverse shear and torsion loads.
      • Stresses calculated using shear flow theory.
