Aug, 2016 Dave Schubert, P.E. Articles, Structural Practices. In the engineering and construction industry, any truss spanning more than 60 feet is considered to be long span, thus requiring engineering consideration (per International Building Code (IBC) 2015 Section 2303.4, Trusses [for design of]).See all results for this question
What should be the spacing of a primary truss?
Primary trusses are commonly spaced at about one quarter or one fifth of their span but consideration should be given to the form of the secondary elements and roof decking when choosing the truss spacing as it is usual to have no more than two layers of structure supporting profiled roof sheeting.See all results for this questionWhat kind of trusses are used in long span buildings?Some of the commonly used types are shown below. Pratt trusses are commonly used in long span buildings ranging from 20 to 100 m in span. In a conventional Pratt truss, diagonal members are in tension for gravity loads. This type of truss is used where gravity loads are predominant (see below left).See all results for this questionWhat is the span to depth ratio of trusses?The span to depth ratio of trusses ranges from 10 to 25, depending on the intensity of the applied load. The lower the ratio, the longer are the shear members in the truss and the larger is the volume occupied by the roof structure.See all results for this question

According to the project characteristics, the construction scheme of the roof steel structure follows the principle of subareas and substeps, with the truss lifting in segmentation. To ensure construction safety, a construction monitoring scheme was adopted in this project. According to the layout of the roof steel structure, a total of 10 monitoring points are arranged See more on hindawi steel space truss long span structure pipe truss boringTerminal pipe truss roofing-Sinoacme Steel StructureSteel Pipe Truss Structure is a new advanced structure developed from space frame. All parts making up a pipe truss structure are steel pipe bars. The pipe bars are connected by the method of welding, having been cut by intersection line cutting machine in advance.
