  • Corrected erroneous capacity equation references for wood members designed per the CSA O86-14 code.

  • Corrected a units conversion error with the rebar detailing diagram in member detail reports.
  • Fixed an issue where project grids were omitted from the creation of a flat file incorrectly.
  • Improved the column behavior to determine whether a given floor supports a column laterally. Previously the program always assumed a floor level was a lateral support.

• Fixed a metric units issue with Column Forces where they were much higher than they were supposed to be.

• Corrected a bug with the Canadian Composite Rib Height to account for studs being measured above the rib.
• Corrected a problem in the Column Results spreadsheet with spreadsheet value coloring. Previously red coloring was being used for the Lift column rather than the Code Check column. Now code checks greater than 1.0 are shown in red.
• Updated the Composite Deck databases to use the correct self-weight. Previously the weight of the metal deck itself was not included.
• Corrected a problem that was caused by running the envelope solution in RISA-3D under RISAFloor. If there were gravity-only walls and an envelope solution was run in RISA-3D the program would shut down.

  • Update the deck .def file to correct composite design issues.

• Fixed an issue with Joist Girders where the calculation for moment of inertia was off when the units of force were not in kips.
• Corrected an issue with the calculation of tributary area of columns which support continuous beams. The tributary area from the I end of Beam segment had been erroneously assigned to the J end and vice versa.

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.
