The most economical structures are often those produced using plastic design techniques, which in the UK, are well established and have been used for over 40 years.Lattice trusses are typically designed using elastic analysis techniques.The main alternative to portal frame is lattice construction.Lattice trusses are generally more expensive than portal frames for routine applications and spans. However, for certain applications they will offer the best framing solution, such as: for very large spans (greater than 50m), for production facilities needing heavy plant suspended from the roof area, or where deflection criteria are particularly critical.
