Bracing in both directions is necessary at the top level of the simple structure it is achieved by means of a longitudinal wind girder which carries the transverse forces due to wind on the side walls to the vertical bracing in the gable walls. In the second case, (right) each truss and the two columns between which it spans, constitute a simple structure the connection between the truss and a column does not resist the global bending moment, and the two column bases are pinned. Loads are applied to the portal structure by purlins and side rails.

In the first case (left) the lateral stability of the structure is provided by a series of frames formed from a truss and columns the connections between the truss and the columns provide resistance to a global bending moment. Vertical bracing is generally provided on both elevations. Longitudinal stability provided by transverse wind girder and vertical bracing (green). Lateral stability provided by longitudinal wind girder and vertical bracing in the gables (blue) Longitudinal stability provided by transverse wind girder and vertical cross bracing (blue) Lateral stability provided by columns and truss connected to form a frame. Two types of general arrangement of the structure of a typical single storey building are shown in the figure below.

This article focuses on typical single storey industrial buildings, where trusses are widely used to serve two main functions: Trusses are also used to carry heavy loads and are sometimes used as transfer structures. Trusses are used in a broad range of buildings, mainly where there is a requirement for very long spans, such as in airport terminals, aircraft hangers, sports stadia roofs, auditoriums and other leisure buildings. Simplify and optimize the design and construction of a short wall or half wall in residential and commercial cold formed steel framing.Overview of trusses Use of trusses in buildings Select from a variety of common trusses, or create your own truss to design the members, connections, fasteners, and lateral bracing elements.
