Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 11 and may not reflect current program behavior.
As described in , The SDPWS Commentary C4.3.3.4 clarifies what is meant by "same materials and construction" along a shearline such that the material specification does not have to be identical, just that the same class of materials (wood structural panels, fiberboard, gypsum-based materials or lumber sheathing) is employed.
A Design Setting has been added to allow you to force identical material specifications on a shearline, or to allow the same type of material but different details.
In version 10, when you change any of the inputs in the Sheathing, Fastener, or Framing data groups, except for the number of end studs, the program applies the change to all wall on the line. This functionality is retained in Version 11 if the Identical materials design setting is turned on.
If the Identical materials setting is not turned on, then all inputs except for the Sheathing Material change independently for each wall or wall design group on the line.
The Sheathing Material changes independently for different walls on the line only in the following circumstances:
If none of these conditions are met, when you change the Sheathing Material all walls on the line change to have the new material.
If the you change a Sheathing Material such that all walls on the shearline have the same material class, then for other walls than the one selected, the program changes not just the Sheathing Material, but repopulates all the Sheathing inputs that are dependent on it – thickness, plies, OSB grade, nail type, nail spacing.
If you change any of the materials in a wall group, then all walls in that group wherever they are in the building, change to have the new materials.
If all walls must have identical materials, then all shearwalls on a line must have the same wall group. If there are walls on other lines with that wall group, then the whole shearlines they are on must also have that wall group, and change en masse to having the new materials for that wall group.
However, if all materials except for the Sheathing Material can be different on a shearline, then if you change the Sheathing Material, all walls on the line must have the new material, even if they are of different wall groups. All walls on other lines of the same group or groups also must change the Sheathing material, to maintain identical group properties. Then all other walls on those lines must change the Sheathing Material to maintain the same material on the line, and so on. This process propagates in a tree-like fashion throughout the structure.
To give an example, suppose that Line 1 has Groups 1 and 2, with GWB materials. Line 2 has Groups 3 and 4 with WSP, and line 3 has Groups 2 and 4 as well. If you change a wall in Line 1, Group 1 to Fiberboard, then Group 2, being on the same line, will have Fiberboard as well. But Group 2 is on line 3, so Group 4, which is also on that line, changes to Fiberboard as well. But Group 4 is also on line 2, so Group 3, which is on that line, changes to Fiberboard. All groups wind up having Fiberboard.
In the Building Site dialog, there is now a link to the website http://windspeed.atcouncil.org/ that provides maps and address lookups to find the design wind speeds for your area for each risk category. This website also provides 10-, 25-, 50- and 100-year mean recurrence interval wind speeds for serviceability wind loads, to be used for story drift calculations.
A similar link exists for seismic ground accelerations.
The log file which provides load generation and rigid diaphragm analysis details has now been integrated into the program and appears in a window within the program framework. Previously the program invoked the Notepad program to show the log file results. The window is called Load Generation and Torsional Analysis Details. The menu and status bar descriptors have also been updated.
The list of steps helping you to get started using the Shearwalls program has been placed in a scrollable view, and formatted with bold titles for each step. The number of steps had become too large to fit on the screen without a scroll bar.
The On-line Help is no longer accessed from a file installed on your computer; it is now accessed via the Web. The Help will now be updated with corrections and for changes to the program as they occur.
The On-line Help has not yet been updated for the changes for version 11 described in this document. The Help will have the updated descriptions by Feb, 2017.
The Help is now specific to the USA version of the program. References to Canadian design procedures and program operation have been removed.
The message that appears saying your keycode is invalid now directs you the WoodWorks Sales email address.
The three-digit code in the software ID that identifies the software version has been expended to 5 digits.
In the About Shearwalls box accessed from the Help menu:
Misplaced colons and brackets in the design code and standard sections have been removed.
In the sales and tech support sections, email communication has been emphasized over phoning, phone extensions were added, the fax number was removed, and the website is now a link to the site rather than text.
The words WoodWorks Technical Support were mistakenly removed, and have been put back.
Occasionally, when running the software from the network installation the program would fail, giving the following error message: "When running from a server, the initialization files must be in the 'Common Application Data' folder, refer to the documentation for information network installation."
This problem has been corrected.
The following corrections have been made to the Add a New Load dialogue box:
When Wind C&C is selected,
When Apply to… Selected Walls was selected, the From and To location did not update properly so that the load would not be applied to just the extent of the selected wall.
You can no longer apply dead load and building mass loads to an entire building face. These loads are more appropriate to a wall line
For wind shear and seismic loads the Element was always shown to be Face even when applied to a wall line. It now shows the wall line it was added to.
When adding a new C&C load, it is now possible to select "Both ways" for wind direction, as the program now distinguishes between suction C&C loads for both nail withdrawal and sheathing strength, and bearing wind loads which impact sheathing strength only.
The list of input loads has been widened to show the Profile column without scrolling.
In extending upwards in stages, the program created an extra level on the level above the one you selected to extend to, and uses the original block outline to create that level instead of the modified footprint. You could then only extend from that level upwards. For example, extending to level 2 on a 4-storey structure, the program copied the modified footprint to level 2 and added the original footprint to level 3, and placed you on level 3. If you extend to a level below the top, the extra level was placed on the topmost level and the process was complete.
This extra level is no longer added when extending levels in stages, for example if you extend to level 2, the program merely copies the modified ground floor level to level 2 and places you there to proceed.
After restoring all Standard Walls to the ones that originally came with the program using the Default Values setting, the program crashed if there were any standard walls that you had made being used in the project.
Shearwalls now only allows the standard walls to be reset if there are no open documents. If you attempt to reset them with a document open, the program now prompts you to close the open document.
The data group identifying the Wall segment has been changed to Wall, because the data correspond to an wall with openings and possibly several full height segments. The program now outputs shear design results and dimensions for each segment along a wall, so the definition of a wall segment in Wall Input view would conflict with the definition in the Design Results.
The default value for the seismic redundancy factor ρ in the Site Information box is now Calculated, indicating that the program determines this factor on the first design and does a second iteration to re-generate loads. Previously the default value was 1.0, in which case it is up to the designer to detect if the resulting design does not actually change it if the resulting design does not actually have a ρ of 1.0 and change it.
In the roof input form, the roof overhang values were being set to zero when switching from a flat roof to a sloped roof and back again. They are now restored to their previous values.
It was sometimes not possible to view the all the Settings input tabs when medium or large Display Size was selected in Windows. It could happen that you were unable to click the buttons at the bottom that close the boxes.
These boxes have now been reorganized in a shape like that of a typical computer screen, so that the entire box fits in the view regardless of the display option selected.
The Apply button has been removed from the Settings dialog because it had no effect.
The repeated word "design" has been removed from the message box that appears telling you that your structure has changed and your previous design is out of date.
In a message saying that the CAD file had not been imported, the words Windows metafile have been changed to image file, as several types of images are now imported.
The following changes have been made to the data field labels in the View settings, which area now shown in separate Plan View and Elevation View boxes:
The word intervals has been changed to snap increments for consistency with the nomenclature in Display Gridlines, which uses the term snap increment. For Display gridlines, Snap has been changed to snap.
An asterisk (*) has been placed beside those inputs that are not saved to the project file, with an explanatory note at the bottom of the box. These inputs are the zoom increment and the Fit Building… and Fit Window… settings
In the dialog box that allows you to create new hold-downs,
The title table that allows you to enter hold-down data capacities and displacements has been changed from Displacement or Elongation to Design properties, in recognition that it is not just deflection data that are entered, but design capacities as well.
The table now called Design Properties has been widened to allow the headings to be fully visible.
In the Options and Hold-down settings, the word story is now used instead of the Canadian/British storey.
Sometimes the Site Information table, and perhaps others, spilled outside the confines of the page when in Preview mode. This has been corrected.
