Materials and Database

Important Note – These are descriptions to changes implemented in WoodWorks Sizer for version 10.1, and may not reflect current program behaviour.

1. Northern Species for Simpson Hangers (Change 35)

   When Simpson hangers are selected as the support type, Northern Species sawn lumber materials are now available for selection. The program uses hanger resistances based on S-P-F resistance factored by the ratio between the selected species’ specific gravity and S-P-F specific gravity.

   This procedure was provided to us by Simpson

2. Simpson Hanger Database Update (Change 15)

   The database of Simpson Strong-Tie hangers has been updated to the most recent version, dated May 2018. According to Simpson, the following changes were made to the database:

   • Added LSSJZ field adjustable hanger for solid sawn lumber
   • Added HWP and HWPH top flange purlin hangers
   • Removed Some sizes of LF and LT hangers
   • Change downward resistances on some HGUS and HHUS hangers
   • Updated the database to match the C-C-CAN2018 Wood Construction Connectors Canadian Limit States Design catalogue
3. Nordic Lam Materials (Changes 85 and 86)

   The following changes have been made to the Nordic Lam materials

   1. Architectural 24F-ES/NPG Widths

      For 24F-ES/NPG beams, columns and built-up plies in the Architectural grade, 1.75" (44.5 mm) wide sections are now 1.5" (38.1 mm) wide.

   2. Industrial 24F-1.9E Joist Section Sizes

      The following section sizes have been added to the Industrial grade 24F-1.9E combinations: 1.5" x 16" (38 x 406 mm) and 1.5" x 16" (44 x 406 mm).

5. Unavailable Material Project File Crash (Bug 3357)

   Sizer would sometimes show two messages and then crash when it could not find the material database file when opening a saved project file. One reason this occurred was a mismatch between the material name listed in the initialization file and the one in the database file.

   Now, if a material is not found in the database, the program picks the first available material and species, shows just one message, and does not crash.

6. Layers Input for 9-5/8" Deep CLT Panels (Change 79)

   The Layers input in Beam view showed 9 layers when either 9-5/8" deep CLTs panel was selected, however one is for panels with 7 layers and the other for panels with 9 layers. The program now distinguishes between the two depths and allows you to select the 7-layer lay-up.
