Version 10.41

Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 10.41 and may not reflect current behavior.

Released October 8, 2015 with Design Office 10, Service Release 4a to only a limited number of users as the bulk of users were not informed that it was available until service release 4b had already been made.

1. Reporting of Height-to-Width Factor for Design Groups (Bug 3088)

   In the Shear Results table of the Design Summary, the program was reporting the height-to-width factor from SDPWS Table 4.3.4 Notes 1 and 3 for the strongest wall in a design group, rather than the actual wall being reported. The wall capacity and the design ratio reported were also from the strongest wall rather than the actual wall.

   The impact of the bug is more severe for shearlines that are composed of a single wall than for lines with more than one wall. For single walls, the only row in the output table showing results for that shearline has the wrong h/w factor and design ratio. For shearline with multiple walls, the rows in the table for individual walls are correct, but the row at the top showing the critical case on the shearline is wrong. You can see that the individual walls make sense and ignore the shearline row.

   If the strongest wall in the design group has a h/w factor of 1, this h/w factor is shown for shearlines with single walls that have h/w ratios less than 1. However, it is rare for there to be non-conservative occurrence of this bug for two reasons:

   • Walls with low height to width ratios tend to be the strongest ones in the group, because the program needs to compensate for the low h/w ratio with stronger materials.
   • Shearlines with just single walls on them tend to have low h/w ratios (with high factors), because one short wall will not resist the applied load.

   Note that this was a reporting problem only. If the design group includes walls that have unknown values, the program applies the correct h/w factor when designing the shearwalls. It is only when reporting the results that the incorrect values appeared.
