Lateral Restraints in Pre-Fab Timber Roof Trusses
Design vs Installation!
A truss is a very efficient structural member which consists of a group of ties and struts connected to form a structure that acts as a large span beam. The design of the truss is based on a basic principle of force triangulation in a plane resulting in the truss members undergoing axial forces, either tension or compression. The top chords of the trusses undergo compression, due to downward dead, live and service loads, whereas for the wind uplift load cases the bottom chord effectively undergo compression. Similarly, the webs undergo tension or compression depending on downward forces or wind uplift.
