Steel Roof Truss Design Ppt

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.

Steel roof truss design ppt.

Economy is achieved as strength to weight ratio is more. This reduces the time it takes to get to the project site. Beams columns braces plate trusses and fasteners. 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.

While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. Structural steel the structural elements that make up the frame that are essential to supporting the design loads e g. Gable lean to and header. Roof truss strength derives from the triangle shapes that comprise the truss itself.

The skeletal structure of a roof system 18 0m long and 7 2m wide is as shown in figure below. 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. Advantages of metal roof truss structures 1. 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.

Metal roof trusses can be manufactured to exact standards. They are much more lightweight and this allows for larger shipments. Triangles are naturally rigid geometric shapes that resist distortion. You can use the links below to navigate throughout the guide.

Advantages of tubular sections. The truss is made up of howe truss configuration spaced at 3m intervals. 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. 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.

Structural shapes standard steel configurations produced by steel mills such as wide flanges channels angles pipe tubes etc. Even though they are considered to be more expensive metal roof trusses can span further than wood. If you re looking for a complete guide for roof trusses then you ve come to the right place. Steel trusses come in three types.

Some of the steel roof trusses generally used are king post queen post fink howe pratt warren fan and north light. Options to set the roof girders on wood post or concrete wall also available.
