Long-span roofs are often associated with iconic projects, be they stadia, airports or other major public buildings. For us as building designers they are often quite unique in the level of integration and honest expression of their architecture and engineering, from the visual drama to the creation of adaptable, multi-functional structures. Long span roofs are also referred to as roofs that exceed a 12 m span. Long span roofs can produce resilient, column-free interior areas. They can also decrease substructure expenses and production times. Long span roofs are usually observed in a broad variety of building varieties such as: Manufacturing plants Warehouses Agricultural structures

Articles In Depth Top Articles 5 Long Span Structures with Awesome Roofs Architects sometimes feel restricted when designing spaces with long-span structures. Generally, the maximum span for beams in building construction depends on the beams' material compositions along with their vertical and horizontal thicknesses. The measurement of a long span roof is at least 12 meters long (the standard length according to PNS 67), which is longer than regular roofs. Some believe 14 feet to be typical. However, anything longer than 14 feet is considered a big spread. The long span minimum length for on-site roll forming might be 12 meters.

Nature Long-Span. By. Lawrence G. Griffi s, P.E. The design and construction of long-span roof structures requires a blend of skills from the structural engineer not normally required in more normal building types. Forces come into play, including material shrinkage, support settlement, temperature effects and sequence of erection, that can. Long span roof - Designing Buildings - Share your construction industry knowledge. Long span roofs are generally defined as those that exceed 12 m in span. Long span roofs can create flexible, column-free internal spaces and can reduce substructure costs and construction times. They are commonly found in a wide range of building types such as factories, warehouses, agricultural buildings. The span of a roof is an important consideration, among other factors, including functional requirements and considerations of speed and economy of assembly. This can be classified in relative terms as short (up to 7.5 m), medium (7.5 m - 25 m) and long (more than 25 m) according to (Foster and Greeno 200. For a long span roof utilizing multiple seamed pan lengths, transverse seams are required. For roof slopes less than 6" on 12", the upper roof pan is attached to a locking strip soldered to the lower pan. The lower pan is cleated to the roof deck with the indicated clearances determined by expansion calculations. See Example Table 8.8A.

Imagine you're designing a long span roof for a sports arena with a span length of 100 feet. You expect a dead load of 10 pounds per square foot (PSF) and a live load of 40 PSF. The roof pitch is 5:12 (meaning it rises 5 units for every 12 units horizontally). You plan to use steel trusses for support. PRODUCT NAME American Long Span III Panel for roof and wall applications.

Rafter Framing The span tables on this page cover the following two design scenarios: Rafters with ceiling not attached to rafters, live load = 20 Psf, dead load = 20 Psf, deflection limit L/180. Rafters with ceiling not attached to rafters, ground snow load = 50 Psf, dead load = 20 Psf, deflection limit L/180. 20 examples of buildings with impressive spans.
