Yachihe Bridge is a record‐breaking cable‐stayed bridge with 800m steel truss deck in the main span. As the bridge side spans are limited in size due to environmental constraints, 220m concrete decks are the optimized solutions for the side spans to balance the weight of steel truss deck in the main span. The joint of concrete deck and steel truss deck is one of the most complex points of the bridge, as it bears the maximum axial force and the structural cross sections, rigidities and material properties are changed at this position. This paper mainly presents the detailed design and numerical analysis for the steel‐concrete joint of Yachihe Bridge to investigate its structural performance. Meanwhile, the numerical results of concrete and steel decks, bearing plate and shear studs of the joint are also discussed. |
