Truss: Truss are structures consisting of straight slender rods connected only at their ends.

Truss:

Types of Truss: • Plane truss: Plane truss is defined as a two dimensional framework of straight prismatic members connected at their ends by frictionless hinged joints, and subjected to loads and reactions that act only at the joints and lie in the plane of the structure. The members of a plane truss are subjected to axial compressive or tensile forces.

Members connected at their ends by frictionless hinged joints, and subjected to loads and reactions that act only at the joints and lie in the plane of the structure.

Types of Truss: • Rigid truss: • A plane truss is rigid if it does not change shape when subjected to a general system of forces at it joints. . The simplest stable or rigid form of a truss is a triangle, which is the basic truss element: To prevent collapse, the form of the truss must be rigid.

Types of truss: • A simple truss is a planar truss which begins with a triangular element and can be expanded by adding two members and a joint. For these trusses, the number of members (M) and the number of joints (J) are related by the equation M = 2 J – 3.

Classification of truss: • Truss: • 1. Perfect truss: • 2. Imperfect truss: a. Redundant truss b. Defficient truss
