What is a diagonal steel truss bridge?

Inclined-leg steel truss bridge, as the name implies, the rigid frame legs are inclined, and the axes of the two legs and the middle of the beam are roughly arched. In this way, the bending moments on the legs and beams are significantly reduced compared with the portal frame of the same span. The axial pressure has increased. Compared with deck arch bridges, this type of bridge does not require an upper arch structure, and the number of components is small; when the bridge deck is narrow (such as a single-track railway bridge) and the span is large, its inclined legs can be placed on the lateral side of the bridge. To ensure the lateral stability of the bridge.

So, are there any truss bridges that are the models of inclined leg truss bridges?

The famous pre-stressed concrete inclined leg steel truss bridges include: Federal Germany Horem Railway Bridge (1953, leg hinge span 85.5 meters), China Handan (Dan) Chang (zhi) Railway Zhuozhang River Bridge (1981, foot hinge The span is 82.0 meters), the French road bridge of Saint-Michel (in 1957, the span based on the center distance of the piers is 1×60+5×65.2 meters) and so on. Famous steel oblique-leg steel truss bridges include: Luxembourg Alzette Road Bridge (1965, hinge span of 234.1 meters), Yugoslavia Neretva Railway Bridge (1966, 100 meters), France Martigues Road Bridge (1972 Years, 210 meters), Italy's Sfalasha (376 meters) road bridge (1972, 376 meters), and China's Ankang Hanjiang railway bridge (1982, 176 meters), etc.
