Part 5: Detailed Design of Trusses 5 - vi SUMMARY This publication provides guidance on the design of trusses for single-storey buildings. The use of the truss form of construction allows buildings of all sizes and shapes to be constructed. The document explains that both 2D and 3D truss forms can be used. The 2D form of truss is essentially a beam and is used to supporting a building roof, spanning up to 120 metres for large industrial buildings. The 3D form of truss can be used to cover large areas without intermediate supports; this form is often used for large exhibition halls. The detailed guidance in this document relates mainly to 2D truss structures composed of rolled profiles but the principles are generally applicable to all forms of truss structure.
