| Abstract: | Taking hoisting construction of Yanghe bridge＇s arch rib in Suqian city as engineering background, it analyses the selection of hoisting method and suspension position. Moreover, it proposes an integral hoisting method which weld the rigid framework of the tie bar, outer steel tube of the suspender with the steel tube of the arc rib together. Solutions on stress concentration dispersing and the possible buckling intabilization checking during the process of hoisting are brought forward as well. |
