Released December 21, 2007 with WoodWorks Design Office 7
The changes to Shearwalls for Version 7 listed below take into account the changes in the National Building Code of Canada (NBC) for the 2005 Edition vs. NBC 1995. These and other changes are also taken from the January 2003 Update and the January 2005 Supplement to the CSA O86 Standard. Further information was taken from the NBC Structural Commentaries.
Many other changes, not related to new design codes, are also listed. The following are highlights of the changes, with links to the full description in the subtopics of this section.
Design Code Updates
The program implements the new procedures for National Building Code of Canada (NBC) for the 2005 Edition, replacing those of NBC 1999, for both wind and seismic load generation.
Other changes are taken from the January 2003 Update and the January 2005 Supplement to the CSA O86 Standard, and further information was taken from the NBC Structural Commentaries.
Seismic Irregularities
The program now analysis the structure for irregularities according to NBC Table 4.1.8.6 and other parts of NBC 4.1.8. It outputs a of seismic irregularities, detects the irregularities in the structure, and informs you when the regularity invalidates design, identifying the precise location of the irregularity and the reason for design failure.
Undo/Redo Feature
The program now allows the user to revert graphical input operations in the interactive Plan View and data input operations in its associated input forms, and to restore the actions that were undone.
Building Model Improvements
The program now allows you to exclude shadowed portions of the roof and walls when generating wind loads, allows up to six building levels , and allows CAD import on each level.
Load and Force Distribution Improvements
The program has implemented and for hold-down and compression force calculations, allows you to specify for drag strut calculations, and has updated the accidental eccentricity factors for rigid distribution.
Improved Graphics
There are now explanatory legends in Plan view and Elevation view, a view showing all the in one diagram, depiction of vertical load transfer elements, and improved layout of forces in Elevation view.
Enhanced Output Reports
The program has a new output report viewer with formatted, graphical output organised into easy-to read tables. It also allows such features as navigation tools, zooming, page range printing, and file output to .pdf or .rtf files. All tables have been provided with explaining the headings, the data, and certain design assumptions.
Documentation
An up-to-date version of the On-line design standard in .pdf format has been provided. The on-line help has been updated to reflect the current program and converted to Vista-compatible . The current design codes are displayed in the user interface and design reports.
Bugs
Numerous problems with program operation have been resolved, in the following areas: wind load generation, seismic load generation, modelling the structure, user input, load and force distribution through the structure, shearwall design, graphics, output of design results, and file operations.
Important: You may need to re-examine past projects in light of these issues.
