Long span truss, its types, materials used, connections, advantages, disadvantages, case study LONG SPAN TRUSS • A truss is essentially a triangulated system of straight interconnected structural elements. The most common use of trusses is in buildings, where support to roofs, the floors and internal loading such as services and suspended ceilings, are readily provided. • The main reasons for using trusses are: 1. Long span 2. Lightweight 3. Reduced deflection (compared to plain members) 4. Opportunity to support considerable loads. TYPES OF LONG SPAN TRUSS • Pitched Roof Truss • Lattice Girder • Parallel Chord Truss • North Light Truss • King Post Truss • Vierendeel Truss • Queen Post Truss • K - Type Truss • Pratt Truss • Pitched Roof Truss • Howe Truss • Fink Truss • Fan Truss • Scissor Truss • Warren Girder ADVANTAGES • Very long spans possible • Heavy loads may be carried • Modest deflection DISADVANTAGES • Generaly more expensive fabrication • Bracing is used for in plane stability
