Long span spatial structures systems provide large areas of open floor space with fewer interior columns. Freedom from interior obstructions allows maximum use of space and operating efficiency. This offers a clean, uncluttered space, ideal for warehousing and distribution applications. Structure with Span larger than 40 m can be regarded as long span spatial structures and need to be carefully designed keeping a balance of all the aspects like its weight, deflections (sway) and foundation forces. There are many combinations of designing large spans, like conventional truss & RCC column combination, truss & steel columns, Pre-engineered building (PEB) etc.
