A roof truss is a triangular shaped two-force member structure made of dimensional lumber designed to withstand anticipated loads at your building site. Loading, like snow load, wind, loft, ceiling, or attic loads are all considerations when a truss is designed.
Large loads on either cord (top or bottom) can impact the size of the dimensioned lumber used, not only on the large load side, but on the other side as well. Temporary truss bracing is critical to ensure safety and to protect the integrity of the truss structure until permanent bracing is in place.
Connecting the truss to your building is critical to long term strength, durability, and safety. Post frame buildings have some advantages that are important to consider in your construction methods.
Truss to Post Connection OptionsDepending on what part of the country you live in the method of attaching the trusses (or rafters) to the posts will be different.
The method most widely used in the northwestern part of the United States is the direct attachment of trusses to the structural posts.
Many times in the southeastern part of the United States, you will see a header attached to the structural posts. The trusses (or rafters) are then placed on, and rest on, this header board and are attached by fasteners. Glue Laminated columns (posts), also called GluLams, are becoming more affordable to manufacturer and provide stronger resistance to wind and snow loads.
In some parts of the country, glulam posts are even more economical to buy than solid posts. These glulam structural posts can be manufactured to accept trusses or rafters at the top of the post. The trusses or rafters are placed on the sides (or sometimes the middle) of the glulam post.
Another method employed by some contractors is to notch the structural post at the top and place the trusses (or rafters) on top of the notch. This method is commonly used on pole barns that use round posts (often called telephone poles). The notch allows the truss to not only rest on the pole but to also seat properly against to the pole to provide a well formed connection.
