Simple Steel Roof Truss Design

It is desired to specify the appropriate angle sections that will safely carry the anticipated loading using eurocode design code specified steel grade s 275.

Simple steel roof truss design.

While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. Different steel roof truss designs are prepared depending upon the shape of the structure. There are parallel and triangular and trapezoidal trusses. To illustrate this a simple design example has been presented.

Here is your complete guide. Aspects of truss design for roofs truss or i beam. Use a simple king post truss to reinforce small lightweight structures. The skeletal structure of a roof system 18 0m long and 7 2m wide is as shown in figure below.

After that the external load is to be estimated including the self load of the truss. There are many ways of arranging and subdividing the chords and internal members. The top chords typically bear loads directly and the resulting tension and compression load distribution through the struts to the bottom chord accounts for the greater overall load bearing capability. This style is useful for framing structures that don t require quite as much support as structures that bear more weight.

The fink truss offers economy in terms of steel weight for short span high pitched roofs as the members are subdivided into shorter elements.

A king post truss design features a single vertical joist that runs through the center of the triangular frame. The truss is made up of howe truss configuration spaced at 3m intervals. Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.
