Zero-Force Member

A truss is a framework that comprises slender members connected at their ends by joints. Trusses are widely used in engineering and architecture to stabilize and strengthen structures like bridges, roofs, and towers. Truss members are designed to carry loads through tension and compression, enabling the truss to withstand external forces.

A truss member that experiences no stress under loading conditions is called a zero-force member.

For a truss joint with two non-collinear members and no external load or support reaction, both members must be zero-force members.

A free-body diagram is drawn for this joint. The sum of the forces along the vertical direction equals ...
