Curved roofs are typically supported by:

Curved roofs are typically supported by bowstring trusses or arches due to their design characteristics that effectively distribute loads while allowing for the architectural flexibility needed in such structures. Bowstring trusses have a unique shape that combines both tension and compression, making them well-suited for spanning large areas without the need for additional support columns. This design is particularly beneficial for curved roofs, as it not only provides strength and stability but also allows for aesthetic appeal in buildings such as gymnasiums, sports arenas, and other large-span facilities.

Additionally, arches are effective structural elements for curved roofs because they can carry loads efficiently, distributing the weight evenly along their curve, which enhances the overall stability of the roof. This combination of bowstring trusses and arches ensures that the roof can withstand various environmental loads, such as wind and snow, while maintaining its curved shape.

While other trusses like parallel chord, heavy timber, and pitched chord also serve specific roofing needs, they are not typically used for curved roofs as effectively as bowstring trusses or arches. Parallel chord trusses have a flat or level design that does not support curvature, while heavy timber trusses and pitched chord trusses are more straightforward in design and typically serve different roofing applications.
