Note: These highly simplified tables are based on common grades of timber, fixed truss and purlin centres, and do not take the truss configuration and pitch into account. They are provided only to enable the architect to complete his drawings. MiTek truss designers may well achieve a more economical solution at design stage.
INDUSTRIAL TRUSSES - ECONOMIC PROFILES
Large spans can be achieved in timber, provided a minimum ratio of span/depth is achieved. With sufficient height, spans of up to 28 metres have been built, often at considerable savings over other forms of construction. Several large shopping centres have been successfully designed and erected using large span timber trusses.
