Version 20.00.003

Released May 14th, 2021

Added:

  • Dutch language version
  • National annex to Eurocode: Belgian
  • National annex to Eurocode: Dutch

Modified:

  • Cdir value used in wind load calculation has changed from 0.85 to 1.00 in Hungarian National Annex.
  • Estonian national annex change in EN1992-1-1:6.4.5(3), formula 6.53 is implemented.

Fixed:

  • At RC bar manual design, displaying interaction surface for fire combination could have caused crash.
  • Bedding modulus calculation caused crash if model already contained punching reinforcement.
  • Creating shell reinforcement by "Pick existing region" option created more reinforcement region if shell was supported by surface support.
  • During saving to StruXML some point and line supports were saved wrong.
  • In Steel joint module reinforcement quality was not selectable for anchor bolt material.
  • In wind load generation dialog buttons in the bottom were not visible.
  • Modelling tools layer was not automatically turned on when Fictitious shell command was launched.
  • Moving load influence line results may have caused crash if the selected point was at the border of two structural objects.
