Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 9.1 and may not reflect current behavior.

1. Total Wall Shear Force in Shear Results Output (Bug 2301)

   If you do not specify in the design settings to distribute forces to wall segments based on rigidity, then the total shear force V on a wall reported in the shear results table is mistakenly divided by the length of the wall in inches, yielding a very small number. This does not happen if you set the rigidity method to be “Equal rigidities”, but does for the other three options.

   This had no effect on loads analysis or design, it was just a problem in tht output form.

2. Hold-down Type and Capacity Reporting (Bug 2319)

The hold-down type and capacity reported in the hold-down output table was sometimes giving the values for the left side of the wall segment for the right side, and vice-versa. This had no effect on load distribution or shearwall design, it was just a reporting error.

1. Duplicate Case 1 Wind Loads (Bug 2179)

   When Case 1 Wind Loads and ASCE All Heights Method is selected in the Design settings, each wind load was duplicated in the Loads able of the Results report and the log file.

   They now appear only once.

2. Repeated Rigid Diaphragm Analysis in Log File (Bug 2314)

   When a design is run on a structure, the Rigid Diaphragm Analysis data was being output twice in the log file. It is now output only once.

3. Rigidity Method Descriptor in Design Settings Output (Bug 2321)

   In output of the descriptors for the “Shearwall rigidity per unit length” design setting did not take into account that the program longer uses walls designed for flexible analysis to determine rigidities, and also used the same expression for deflection-based analysis as was used for capacity-based.

   New descriptors have been made to accurately describe the options.

4. Log File Torsional Rigidity Output and Units (Change 90)
   • The notation of the units for the torsional rigidity due to the stiffness of a shearwall based on deflection has been changed from kips/in-ft^2 to kip-ft^2/in.
   • Scientific format was used when the torsional rigidity value was > 1.0 ^6, now scientific format is used only if the torsional rigidity is greater than 10⁸
5. Warning for Hold-down Displacement from Override (Change 94)

   A warning in red has been added under the Hold-down displacement table if any of the displacements in the table have been taken from the over-rides in the Hold-down settings because there is no

6. Drag Strut Force Direction (Change 89)

   Drag strut forces in the E->W direction were reported in the column for the W->E direction, and vice-versa. This has been corrected.

7. Allowable Storey Drift Units (Change 88)

   In the Story Drift table, the Delta a column header for allowable storey drift gave the units as feet when the units are actually inches. This has been corrected.

8. Warning for Zero Capacity Seismic Design Categories (QA Item 8)

   When a material had zero capacity because it was not allowed for the Seismic Design Category, the program placed two asterisks in the Critical Response column, with no explanation for these asterisks. Now a warning appears below the table explaining the reason for them.

9. Hold-down Design and Drag Strut Table Legends (Changes 77, 79, 83, 101, 102)

   In the legend for the Hold-down Design table

   1. Earthquake Forces
      • Changed "Vert E" to Ev and "vertical earthquake load" to "Vertical seismic load effect" be consistent with ASCE terminology
      • Added notes explaining the horizontal load effect Eh from ASCE 7 12.4.2
   2. Load Combinations
      • Added note for load combination used from ASCE 7 2.4.1.
      • Added 0.7 factor in description of shear overturning component
   3. Vertical Elements
      • Changed “Vert Elem” to V Elem, to accord with heading
      • Added vertical element explanation to “Line-Wall” description.
   4. Other Clarifications
      • Added Position of. before stud that hold-down is attached to
      • Change * multiplication symbol to x

      In both the legend for the Hold-down Design table and the Drag Strut Table:

   5. Applied Load or Sheathing Capacity

      The program now indicates in the legend whether the hold-down design force shown is based on applied shear force or shearwall capacity. A setting in the Design Settings controls this.

10. Deflection Table Legend (Change 79 )

    The Wall Group item has been explained more fully.

1. Elevation View Graphics
   1. Long Hold Down Symbols for Zero Joist Depth (Bug 2102)

      In the elevation view, the hold-down symbols were extremely long when the joist depth the symbol spans is zero. The symbols are now drawn about 4" long in that case.

   2. Vertical Seismic Force in Elevation View Legend (Bug 2145)

      The portion of the legend in elevation view that shows the load combinations S - D (tens) and S + D (comp) has now been revised to include the vertical seismic load effect Ev. The legend now says S - D + Ev (tens); S + D + Ev (comp).

   3. Shearwall Material Options for Elevation View (Bug 2150)

      In the Display group in the Options Settings, and the corresponding menu items in the Show menu for Elevation View,

      • The “Nailing” choice was removed because the nailing is on the same line as the sheathing.
      • An item has been added to turn on and off the legend, to allow for more vertical space.
   4. Factored Dead Load Component of Compression Force (Bug 2155)

      For compression forces at hold-down locations, the dead component displayed in Elevation View was factored by the uplift factor (0.6) instead of the gravity factor (1.0).

      The correct factor is included when the hold-down forces are combined, and it is the unfactored force that is distributed downwards, so this problem had no effect on hold-down design or deflection analysis.
