Connections 2002

Nov 18, 2002 - Design Office 2002

1. Lapped Splice Bolted Connections

   The generalised geometry currently used for nails is extended to bolts. The program designs right angle connections with loads in both directions, sloped connection with load parallel to the side member, and splice connections using bolts. It automatically places the bolts in the intersection of the members according to the spacing rules.

2. Wood-to-Wood Bolted Design

   The program determines resistances for wood-to-wood lapped splice connections. It previously designed only steel to wood connections for bolts.

3. Steel-to-Wood Lapped Splice Connections

   For both bolted and nailed generic connections, it is be possible to design a steel plate entirely within the boundary of the wooden member. This facilitates splitting of complicated connections into their component parts.

4. Three-member Connections

   Bolted connections are able to have two steel or wood side members with a wood main member, or a steel main member with wood side members. Three wooden member nailed connections will be implemented.

5. Ledge Connection

   A ledge connection has been implemented to allow the user to model a continuous bolted sill plate ledge.

6. Wood-to-Concrete Design

   A connection consisting of a ledge bolted to a concrete wall has been implemented.

7. Greater Range of Angled Connections

   For both nails and bolts, there will be a larger sweep of angles possible in the "skewed" connection. The user can specify and angle from zero to 180 degrees, making it possible to design trusses more accurately.

8. CSA O86-01 Design Standard

   The program has been updated to conform to CSA O86-01 design standard. These changes include:

9. Fire Retardant Factor

   O86 10.2.1.7 requires that tests be performed by the manufacturer of wood treatments and the resulting effects on strength be published. Thus, the fire retardant combo box has been changed to have one option - [not active] or the user may enter a value between 0.1 and 2.0.

10. Jc Factor

    Table 10.3.3B giving values of Jc for end distances in tension, the headings have changed such that Jc no longer depends on number of shear planes.

11. Steel Strengths

    The value of embedding strengths for steel used in the program have been changed to 1435.71 and 1615.17 for ASTM 36 and G40.21M 300W steel grades respectively, according to O86 10.4.4.2.

12. Lumber Densities

    Relative densities of lumber updated to conform with Table A10.1
