Web2 dec. 2024 · The Pratt truss required more iron than a Howe truss, and due to the increased cost and less rigid construction, builders did not extensively use it for wooden trusses. However, as the cost of iron declined, its popularity increased, and it greatly impacted metal truss bridge design. Web10 jun. 2010 · Real-world trusses can’t be optimized the way a balsa wood bridge can, because real-world trusses have to carry many different combinations of load, and a truss optimized for one set of loads won’t be optimal for another set. Still, even when they can’t be fully optimized, trusses are usually much lighter than alternative structures. simplehuman trash can package
