v3.6.1.0

12 Aug 2020
Torsion Bug Fixes

  • Slender Spandrel method is now accounting for bearing length

10 Aug 2020

  • Fse for transfer length now uses the lose computed at the center of the strand
  • 'd' is now computed for sections where the reinforcement has no effective area (fully undeveloped)
  • Added options to ignore loading on cantilevers to assist in modeling simply supported members
