By quantifying truss efficiency, engineers, architects, and builders can make informed decisions regarding materials, design modifications, and load-bearing capabilities.

A truss is inherently stable in shape and resists load by developing primarily axial forces which might be tensile or compressive in nature. The connections in trusses are always assumed to be nominally pinned. When the connection of trusses is stiff, secondary effects such as bending moment and shear force are induced in the truss members.

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.
