Maximum span of inclined leg rigid frame bridge

290 meters. The new open-web rigid frame bridge is a new type of rigid frame bridge proposed and patented by Zhongjiao No.2 Highway Survey and Design Institute in recent years. Compared with the general vierendeel bridge, the new vierendeel rigid frame bridge has a large opening height and a long lower chord. By setting inclined legs near the root of box girder, the structural stiffness in the root area is increased. Located at the junction of Faer Township and Yingpan Township, Shuicheng County, Liupanshui City, Qianxi, it has a total length of 126 1 m, a maximum pier height of 170 m and a maximum span of 290 m.. The main span of the bridge is a 290-meter prestressed concrete open-web (inclined leg) continuous rigid frame, which is the first open-web continuous rigid frame in the world.
