The decks are joined at intervals along their length by stiff transverse girders 22 and intervening diagonal shear braces so that the two decks behave essentially as a single rigid body in regard to torsional movement. This results in very high aerodynamic damping of both torsional and bending ...
The Liaozi large-span bridge, an important control project of the Yinchuan-Baise Expressway in southwest China's Chongqing Municipality, was successfully connected on August 29. The 330.8-meter-long structure in Liaozi Town is China's first long-span bridge to adopt arch rib multi...
