Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 9.1 and may not reflect current program behaviour.
Released on October 29, 2014 with Design Office 9, Service Release 1b.
For saved project files, the Accept Design button was defaulting to accept flexible wind design, instead of the currently selected load case and distribution method. If there were no wind loads the Accept Design button had no effect. This has been corrected.
The program was producing different rigid load distributions and wall designs on consecutive design runs for the Use shearwall capacity to approximate rigidity rigid distribution setting. None of the design runs could be assumed to be correct due to instability in the updating of segment rigidities. This has been corrected.
After pressing the Accept Design button the relative rigidity in the Wall Input view was showing 1.0 instead of the rigidity from the accepted design wall.
This is just a display issue and the correct rigidity was used in design. It has been corrected.
When imperial units are used, the shear rigidity Bv value for gypsum wallboard shown in the sheathing information table of the design results was the correct value divided by 12. This was a display issue only and did not affect design. It has been corrected.
Note that this value comes from the USA SDPWS in the absence of Canadian guidance.
When the Wind directions S->N, E->W and N->S, W->E are selected in the Show menu, the Rigidity shown in Wall Input view was a nonsensical value. This was a display issue only and the correct rigidity was used in the shearwall design. It has been corrected.
If only rigid diaphragm analysis is selected in the Structure Input view, the program shows failure for non-shearwalls in elevation view, even if the walls are strong enough to resist design. In the Components and Cladding table, the program showed a warning that these walls do not have shear resisting materials, even If they did.
This problem disappeared if you chose to do both rigid and flexible design. It has now been corrected.
Occasionally when wind loads with zero magnitude were generated on single faces of buildings with flat roofs. This problem occurred only sporadically and has been corrected.
When selecting a standard wall to assign to a physical wall, the number of wall studs was not being accounted for, so that if there were two standard walls that were identical except for the number of wall studs it sometimes would cause the program to assign the wrong standard wall to the selected wall. It was also not possible to select one of the standard walls in the Edit standard wall view.
Whether or not it happened depended on the order of the near-identical standard walls in the list of walls. It has been corrected.
Sometimes extra, unnecessary design wall groups were being created with a nail penetration depth 1mm larger than another wall group, when the walls should actually be in the same wall group and have the same nail penetration depth. This occurred only sporadically and has been corrected.
In wall input view, if you selected "Both sides the same" and specified unknown values, and then deselected Both sides the same, the unknown values were still recorded in the interior sheathing, even though design for unknowns is not done independently for interior sheathing. If these unknown values were not changed, the program would design using the weakest materials in the list, and would show question marks (?) in the Wall Design Groups output table for the interior sheathing.
Now, when you deselect Both sides the same, the program changes any unknown values on the interior surface to the weakest possible. Unless changed, these materials now show up in the Design Group Output.
Starting with version 9, the program would sometimes crash after designing a structure in which some wall lines are entirely non-shearwalls, and some other lines have walls do not have sufficient shear capacity to resist the applied force. This has been corrected.
The program now records the version of the program used to save a project file and shows it in the About Shearwalls box when the file is opened. This feature is primarily used internally at WoodWorks for diagnostics.
