Released with Design Office 7, Service Release 1 - July 28, 2008
This is a free service release update to address issues submitted by our users since the release of version 7.0 in December, 2007 and also to implement non-critical bug fixes and small improvements which previously had been deferred.
A: Shear Wall Design
1. Crash on Design of Short Shear Walls (Bug 1839)
Performing a design on a structure that contains a shear wall that does not contain any shear wall segments that meet the minimum height-to-width restriction was causing the program to crash. This has been rectified.
2. Pj and Ptop Values in Calculation of Jhd Factor (Bug 1841)
When both dead loads and "dead wall" loads are present on the same wall, the program was not separating the dead and dead wall loads when calculating uplift restraint forces Pij and Ptop in CSA O86 9.4.5.2 and 9.4.5.3, causing these values and therefore hold-down effect factor Jhd to be incorrect.
3. Rj Value in Calculation of Jhd Factor (Bug 1842)
In the calculation of the overturning force Rj used in calculating uplift restraint forces Pt and Pj in O86 9.4.5.2 was incorrectly subtracting the 150mm old-down offset that was introduced in version 7 from the segment length L. This caused the hold-down effect factor Jhd to be slightly smaller than it should be on all levels except the top level.
4. C&C Results in Elevation View for non-shearwalls (Bug 1832)
When a non-shear wall is loaded with Components and Cladding (C&C) wind loads, in Elevation View the program was displaying design parameters as unknown, and both the capacity and load as zero. In the Design Results, the materials and the C&C design results are correctly displayed. Both areas of the program display now display the correct C&C design results.
5. Alternating Wall Designs (Bug 1840)
Running a design on a structure with walls loaded in only one direction, the program was generating two sets of designed materials, which would alternate each time design was invoked.
6. Seismic Allowable Shear Capacity Zero (Bug 1652)
Saving prior to designing a structure with narrow wall segments caused the seismic allowable shear capacity to be calculated as zero in Elevation View and the Design Results report. However, running "Design" immediately after opening the project yields a valid non-zero seismic allowable shear capacity.
B: Load Distribution
1. Vertical Loads on Shear Lines with non-shearwall Segments (Bug 1682)
Manually input dead and uplift loads on shear lines are now included on non-shearwall segments, and distributed to the floors below.
2. Drag Struts for non-FHS Segments (Bug 1683)
Drag strut force calculations were incorrectly adding a force due to non full height sheathing (non-FHS) segments to the adjacent force from an adjacent FHS when the non-FHS segment was at the end of a wall, creating higher drag strut forces than the correct ones, and creating an additional drag strut force location.
3. Lack of Warning for Rigid Non-Design (Bug 1759)
When the program does not have sufficient loaded shear lines using the flexible distribution (I.e. two per direction), so that the program cannot perform rigid distribution, a message box now warns the user of this situation.
4. Torsional Load Case Heading in Log File (Bug 1853)
The heading in the log file for the torsional load cases for rigid diaphragm analysis given by NBC 2005 4.1.8.11 10) i and ii, was mistakenly showing the load cases from the 1995 NBC. It has been corrected to show plus or minus 10% of the building width, as follows:
Torsion Load Cases
+10% Dnx -10% Dnx
1. Wind Load Generation on Multiply-joined Roof Blocks (Bug 1758)
When three blocks were aligned in one direction, and when the "Exclude roof portion cover by other roof" option is checked, for the ASCE-7 medium rise method, loads were not displayed on the screen nor did they contribute to design loads on the structure.
2. Ce vs Ce* in Log file (Bug 1224)
When topographic factor is present, the exposure factor Ce factor is now presented in the log file as C*, as per the NBC design code nomenclature.
3. Seismic Load Magnitude Formatting (Bug 1256)
In the Seismic load table of the results output, the program now outputs 2 decimal places precision for all output.
1. Select All Feature
It is now possible to select all walls while in the Wall Action in plan view for editing and moving, via a menu item in the Edit menu. You can also use Ctrl-A keystroke to do the same thing.
2. Move Structure Feature
It is now possible to move the entire structure, while the Wall action, by
a) being in the Wall action in plan view
b) using the Select All Command
c) pressing the Shift key on the keyboard
d) also depressing the left mouse button
e) selecting a point in plan view and moving the mouse in the direction of the move.
Note that all walls are selected, but the roof moves as well.
3. Meta File and Project File in Separate or Renamed Folders (Bug 1740)
If a CAD metafile is not in the same folder as when it was first imported, the program prompts the user to browse for the location of the CAD metafile to display, but Shearwalls was unable to retrieve and display the file selected by the user. This has been rectified, and you now have the ability to send complete project specifications, including the CAD file, to other WoodWorks users.
4. Upward Extending of non-shearwalls (Bug 1779)
When the Extend Walls button is invoked, non-shearwalls on the first level are no longer copied as shear walls on the top level.
5. Changing Structure Ceiling Depth (Bug 1728)
Changing the ceiling depth of the top floor in the structure input dialog after walls have already been created is no longer incrementing the wall heights of existing walls on the top floor by the ceiling depth.
6. Log Filename Persistence (Bug 1851)
The filename of the log file was not updated when you changed the project file name. Therefore, when a design was run when the project is still called “Untitled.log” it maintained that name, even after the project file was given a more meaningful name. The log file file name is now updated to correspond to the project file's current filename.
7. Rigid Distribution Information Clearing in Log File (Bug 1852)
- The rigid distribution analysis in the log file is no longer being recorded for each design run of the software, when it should be clearing each time.
- The program no longer repeats the title, date and time for each building level. These are now output only at the start of the analysis.
8. Immediate Effect of Default Settings (Bug 1693)
In the Default Settings page, the asterisk indicating immediate effect of Roof Slope was truncated, and for Roof Overhang it was missing completely. They have been restored.
