What type of truss is shaped like an archery bow?

The type of truss shaped like an archery bow is the bowstring truss. This design features a curved top chord and a bottom chord that create a distinctive arc, resembling a bow. The curvature of the top chord allows it to efficiently distribute loads, making it ideal for spanning long distances while maintaining structural integrity. Bowstring trusses are commonly used in the construction of bridges, sports arenas, and large open spaces where unobstructed areas are necessary. Their unique shape not only supports heavy loads but also gives them aesthetic appeal, further enhancing their use in architectural design.

Other truss types, like simple, stable, or web trusses, have their own specific shapes and structural functions but do not have the characteristic curved design of the bowstring truss.
