The system owner’s software is very sophisticated and not only designs the trusses, but also produces quotations, manufacturing information and production data. Advantages of Trussed Rafters

A strip of underlay, at least 600mm wide, should be laid over hips and above the underlay to the main roof.Where underlay laps are not under a batten, an extra batten should be used to prevent the underlay lap opening due to wind uplift. The underlay should be turned up at least 100mm at all abutments to prevent rain and snow being blown into the roof space. Trussed rafters enabled Architects the freedom with the layout of the upper floor by avoiding the need for internal load bearing walls. Consequently, the ground floor layout and upper floor layout need no longer harmonise. Kitchens could be bigger than the bathrooms above them, and bedroom layouts could be independent of the lounge and dining room layout. The Seven Deadly Sins To reduce the risk of freezing and condensation on pipework, the following precautions should be taken:

A purpose-made one-piece flashing and upstand should be used around pipes projecting through the tiling. For a given span, and a set load therefore, the pitch makes a huge difference to the member forces. The diagram above shows an example of the triangle of forces that apply at a support. The vertical component is the load passed onto the support (“the reaction”), the sloping line the top chord force, and the horizontal force. As the pitch flattens the forces are greatly magnified.The design should specify the number of fixings for clay and concrete tiles. Tables 2 and 3 of Appendix 7.2-B contain minimum fixings for tiles. Additional nails and clips may be necessary in accordance with the design. A fixing schedule produced by the tile manufacturer, based on The Zonal Method, is acceptable.

The webs are set out by considering the overall internal triangle. The intersection of the webs with the top chord will normally be at the quarter points. The intersection of the webs with the bottom chord will normally be at the third points of the internal triangle. For small span or for large span trusses, alternative internal configurations are used Connections

However in many other instances trusses are simply laid flat upon the floor. Such a practice is satisfactory provided that the trusses have a firm and level support of the ground. However this again would involve some preparation. When using the following materials, the detailing and workmanship should follow the design and recognised good building practice: This paper seeks to provide a basic understanding of how trussed rafters work, theirs strengths and their limitations. It is hoped that by examining common misunderstandings, costly and awkward modifications can be avoided. Definition Ventilation openings where the least dimension exceeds 10mm should be protected with mesh to prevent entry of birds, etc. Angle ties should be used on hipped roof corners to prevent the wall plates spreading. For heavily loaded hip rafters, eg where they are carrying purlins, dragon ties or similar bracing should be used to prevent hip rafter spread.
