Steel Roof Truss Design
In Structural Engineering, the name “truss” describes a triangular design. A joint framed structure that sustained the inclined, vertical or horizontal loads. A truss consists of angles, channels, plates and eye bars. It is a framework, typically consisting of rafters, posts, and struts, supporting a roof, bridge or other structure. You will find them supporting the roofs of auditoriums, cinema halls, stadiums, railways, stations, airports and others.
When to use a roof truss Roof trusses are characterized by an economic use of construction materials (timber, steel). Composed of individual lightweight pieces, a truss can also provide a considerable advantage in transport and assembly as compared to conventional roof structures. On the other hand, trusses are more labour-intensive and require connection devices.
However, if a greater number of identical trusses can be manufactured, then considerable economies of scale can be achieved. The structural height of a truss is usually larger than the height of similar structures using solid beams. For roofs, however, this is usually no disadvantage as roofs must often – depending on roof cover material used – be higher at the ridge and lower at the eaves to facilitate roof drainage and ensure water tightness.
