Structural Steel Roof Truss Design

Our software can design trusses for.

Structural steel roof truss design.

After that the external load is to be estimated including the self load of the truss. An advantage of the truss design for roofs is that ducts and pipes that are required for operation of the buildings services can be installed through the truss web i e. There are parallel and triangular and trapezoidal trusses. Different steel roof truss designs are prepared depending upon the shape of the structure.

The skeletal structure of a roof system 18 0m long and 7 2m wide is as shown in figure below. As a relatively new building material steel has become especially useful when incorporated into engineered steel trusses and steel plate connected timber trusses. When a roof is to be provided for a building which does not have interior supports and the exterior walls are more than 12 m apart a roof truss will be a convenient arrangement to support the roof. For many single storey buildings sloping roofs on trusses are common.

Design of roof truss should follow the general layout that is prepared first. Light gage cold formed steel structural steel stainless steel and aluminum. Truss design estimating d e is a complete automated solution for the design of aluminum or cold formed steel truss building frames with either sloped or arched roof trusses. The truss is made up of howe truss configuration spaced at 3m intervals.

Top general geometry for efficient structural performance the ratio of span to truss depth should be chosen in the range 10 to 15.
