Study on Design of Cable-stayed Bridge Separate Steel Box Girder for Shanghai Changjiang River Bridge

The main span 730-m double-pylon double-plane cable-stayed bridge, herringbone pylon and separate steel box girder are used for the main channel bridge of Shanghai Changjiang River Bridge. This bridge is all constructed now according to the expressway standard. The bridge deck is designed by the double-way 6-lane and the double-line rail traffic space is remained. The article focuses introduction on the design gist of separate steel box girder, the structural calculation analysis and experiment, and deck pa...
