Connections Tutorial 2 â Beam to Column Bolt ...
Connections Tutorial 2 – Beam to Column Bolt Connection (Canadian) 2.1 Introduction This tutorial goes over the design of a bolt connection between a beam and column. The problem is the same as example 1 on page 272 of the 2015 edition of the Canadian Wood Council Wood Design Manual.

2.5 Re-Designing the Connection Upon reviewing the design results, it can be observed that the yielding resistance governs the design, and that the connection is over capacity by a ratio of 0.61. Alternative designs are possible. 1. Check to see if the connection will pass with a 7/8 inch (22.3 mm) Bolt. 2. Check to see if the connection will pass with a ¾ inch (19.1 mm) Bolt. Modifying the Bolt diameter changes the overcapacity ratio to 0.77 for a 7/8 inch bolt, and to 1.03 for a ¾ inch bolt. Therefore, for this example a more efficient design would be to specify 7/8 inch bolts as opposed to the 1 inch bolts that were originally input.
