Truss Construction
Lightweight Trusses and Other Wooden Members
Fire service has gained more truss knowledge
Contributes to light-weight structures
Allows offsite prefabrication
Satisfies many building requirements
Lighter in weight that solid construction
Provides long clear spans
Can be delivered prefabricated

Truss Construction
What is a Truss?
A framed structure consisting of a triangle or group of triangles arranged in a single plane
Loads applied at intersections of the members will cause direct stresses in the members
Loads applied between these points cause flexural stresses
