  • New: It is now possible to use Swedish national annex EKS 12, BFS 2022-4. (Case 122075)
  • Fix: For a case with point loads situated directly on supports shear forces where wrongly shown which is corrected (case 118310).


Released: 2021-03-02

  • Fix: An issue in the file handling process blocked files saved in 6.5.000 from being opened in 6.5..001, "Unexpected file format" (Case 101734).


Released: 2021-02-26

Released: 2020-08-12

  • Fix: According to the rules for minimum reinforcement for beams and slabs in EC2 it is allowed for secondary elements where risk for brittle failure can be accepted to limit the amount to 1.2 times the required reinforcement. This option has been added (Case 9312).
  • Fix: Total reinforcement due to possible increase with regard to crack- or deflection criterion was not displayed in the printout which has been corrected (Case 50516).
  • Fix: For user defined concrete materials the tension capacity fctd was not affected by a change of the coefficient Gamma_c which has been corrected (Case 59072).

  • Fix: Shear diagram could be incorrectly drawn when large point loads were applied right above supports (Case 90225)
  • Fix: For an example the correct design shear force at a point load was not found due to a problem introduced in the latest version of the program which is corrected (Case 90366).
