Gable trusses are in stocked in a 4 12 slope x 20 24 30 and 40 width and special order up to 50 wide 60 for tubing trusses.
Steel roof truss design ppt.
Roof truss strength derives from the triangle shapes that comprise the truss itself.
7 in the layout of truss systems it is more preferable in terms of economy and efficiency to have the shorter members in compression and the longer members in tension.
Triangles are naturally rigid geometric shapes that resist distortion.
Some of the steel roof trusses generally used are king post queen post fink howe pratt warren fan and north light.
The truss is made up of howe truss configuration spaced at 3m intervals.
It does not include for example.
While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses.

Options to set the roof girders on wood post or concrete wall also available.
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.
The present work includes designing roof truss components for an industrial building using conventional steel sections and tubular steel sections circular hollow section and selecting most suitable section according to its advantages and disadvantages.
A sl series truss is a single slope truss that includes steel girders and steel columns with clear span widths from 10 through 80 with available eave heights of 8 through 20.
If you re looking for a complete guide for roof trusses then you ve come to the right place.
Design of roof purlins 6 for efficient structural performance it is recommended that the truss span to depth ratio be kept between 10 to 15.
Advantages of metal roof truss structures 1.
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.
Structural shapes standard steel configurations produced by steel mills such as wide flanges channels angles pipe tubes etc.
Metal roof trusses can be manufactured to exact standards.
Advantages of tubular sections.
Economy is achieved as strength to weight ratio is more.
Structural steel the structural elements that make up the frame that are essential to supporting the design loads e g.
Beams columns braces plate trusses and fasteners.
When it comes to roof trusses you need to consider everything from design to cost to the pros of using trusses instead of stick framing a roof.
They are much more lightweight and this allows for larger shipments.
Even though they are considered to be more expensive metal roof trusses can span further than wood.
