Sizer 9.15 Service Release Patch

December 12, 2011 – Service Release Patch 1e

This service release was released as a “patch” that could be downloaded into the Design Office installation or the Sizer Stand-alone installation.

2. Proposed Southern Pine

   WoodWorks has added a proposed Southern Pine database file corresponding to each of the dimension lumber database files. This material database contains all the same information as the standard lumber databases, except that the Southern Pine species has revised values, and does not include the Dense and Non-dense grades.

   The revised values are taken from the Southern Pine Inspection Bureau (SPIB) Proposed Design Values, based on the SPIB submittal to the American Lumber Standard Committee (ALSC) in October 2011. These values are still pending approval by the ALSC Board of Review.

3. Southern Pine Support Material Crash (Bug 2340)

   The program would shut down after trying to design any member that has a beam bearing support made of Southern Pine timber. This has been corrected.

4. Saving of Repeated Point Loads (Bug 2348)

   Starting with version 9 of the program, point loads that were created by "Repeating Point Loads", were saved with the project file. This has been corrected.

5. Inconsistency in Shear Design Search vs. Design Check (Change 100)

   Unknown design searches would sometimes report sections as passing, but performing a full design on the section results in a failed design. This was because Sizer was assuming the same load combination would be critical for the design of all sections. However, sometimes the section size does influence the critical loading, such as the distance d for which one ignores the effect of loads in determining critical shear. In rare cases they can cause the critical load combination to change from one section size to another, so that the program is designing for a non-critical combination. This has been corrected and the program determines the critical combination for each section considered

6. Column Self-weight ( Change 97)

   The new load format for self-weight (see Change 80, version 9.1) did not make sense for columns, as it referred to horizontal "weight" and not axial weight. This has been corrected.

7. Glulam E_min Note ( Change 98)

   A note in database editor input for glulam materials states that Emin = 0.528E.

8. Missing Database File for Supporting Members (Change 96)

   If a project had a supporting member with a material type whose database file no longer is active in Sizer, the program would not open. To correct this, a message box informs you that a database file is missing, and you can still design with only the main member bearing being considered for the supports that have the missing material data.

9. Selection of Single Member Width (Change 100)

   The program was selecting “unknown” when there was only choice of width (thickness), when it should have selected the single width. This affects joist and wall databases that have only 2” thicknesses.

10. Concentrated Load Persistence
    1. Default Loads (Change 102)

       Concentrated Loads can now be saved as part of the default loads that were introduced with USA 9.

    2. Save to Project File (Change 103)

       Starting with version 9, the program did not save concentrated loads to file project file. This has been corrected.

11. Spelling, Formatting, and Nomenclature Changes (Change 99)

• “Loadface” changed to “load face”.
• “Supports” changed to “Support” in Bearing table.
• Removed unnecessary capitals in All load combinations (LCs) are listed in the Analysis output.
• Adjust placement of Vf, Mf, Vr, Mr slightly.
• Accuracy of deflection in inches increased to 3 from 2 digits.
  1. Units in Modification Factor Table for I-joists (Change 93*)

     For version 9.12 (Change 90), the program added the units in mpi or psi to the modification factor table heading. Since these don't apply to I-Joists, they were removed for them
