| Abstract: | According to constructional sequence of a stacked concrete-filled steel-tabular tied arch bridge, the single ribs stability of in-of-plane and out-Of-plane and their influence factors are analyzed,compared with a dumb-bell arch bridge with same span. Meanwhile, the stability of stacked tied arch bridge after construction and in service is analyzed, and the model of the whole is analyzed and investigated. |
