The total slip in the many different connections of a truss structure can lead to a significant increase in displacements, which can have more or less serious consequences: It is therefore essential, where truss structures are concerned, to control the effect of connection slack on the displacements. On the steeper sloping portion of the truss, it is typical to have a truss running perpendicular to the plane of the North Light truss, to provide large column-free spaces. Buckling of the member is controlled by applying a reduction factor to the resistance of the cross-section. 
An example of a double (duo-pitch) Pratt truss is shown below. The full use of this advantage is achievable if the height of the truss is not limited by criteria other than the structural efficiency, e.g. Gable style trusses are available up to 50-60 wide by special order, depending on style.

In general, the form of a transverse wind girder is as follows: It is convenient to arrange a transverse wind girder at each end of the building so that the longitudinal members need act only in tension. Although north lights reduce the requirement for artificial lighting and can reduce the risk of overheating, by increasing the volume of the building they can also increase the demand for space heating. The main reasons for using trusses are: The penalty, however, is increased fabrication costs . Disclaimer: Our steel trusses are engineer printed for agricultural uses. This difference is greater for long spans and/or heavy loads. Profile shaping of tubular sections for joint fabrication. Hollow sections are typically connected by welding whilst open sections are connected by bolting or welding, which will usually involve the use of gusset plates. In order to do this, it is often necessary: Truss members are subjected to axial force, but may also be subjected to bending moments, for example, if the chords have been modelled as continuous. Additional loading is available by increasing our framework.
The external forces applied to the system and the reactions at the supports are generally applied at the nodes. Where bolted connections are used, it is necessary to evaluate the consequences of 'slack' in connections. For many exposed trusses, hollow sections are chosen for their structural efficiency and for aesthetic reasons. Each can vary in overall geometry and in the choice of the individual elements.
