Calculate trusses.
In the case of wooden trusses, the ends are connected by making suitable joints or by nailing and bolting whereas in steel trusses ends are connected by bolting or welding. The trusses are also known as ‘pin-jointed frames’. Let us discuss more details on Trusses and see how we can calculate all forces in Truss.
Starting at one end of the roof, mark the first truss flush with the outside edge of a cap plate. Use a level, square, and measuring tape.
