  • Corrections:
  • Corrected an issue where trying to delete unattached points (for models with a very large number of points) could cause the program to crash.

  • Corrected an issue with the Chinese shape database where the x-bar values for channels were incorrect and were preventing code checks from being calculated.
  • Corrected issues with the calculation of wall self weight used for seismic force calculations. Issues were most apparent in base weight calculations and for Masonry Walls with large openings.
  • Corrected an issue with the unbraced lengths where the program was over conservatively ignoring the deck unbraced length for the Lcomp-top.
  • Corrected a memory issue which could prevent the user from printing the Warning Log spreadsheet.
  • Corrected an issue where a wall drawn by the user was not properly remembering its assigned design rules.
  • Corrected an issue with sloped floors where member self weight was being erroneously interpreted as a projected (PY) distributed load.

  • Corrections:
  • Corrected issues with some of the wood I Joist database files which prevented the information from being read in properly.
  • Changed a misleading Warning Log Message to be more descriptive. Instead of "Not enough solution data", the message will now inform the user that their results were generated by an older version of the program.
  • Updated notation for design coefficients for EuroCode. Previously, the EC3 2004 code was mistakenly using the naming convention from the 1992 version of the code.
  • Corrected an issue where pinned end joists could erroneously report a moment reaction at the end of the joist.
  • Corrected an issue where unbraced lengths with blank entries were being read in as if their unbraced lengths were set to "Segment".
