| Abstract: | Newly-built Beigang Bridge in Dalian is a girder and arch combination bridge with non-horizontal beam deck. According to its load features in construction process,this paper simulates the construction process with planar bar system＇s finite element model and optimizing tension sequence,and forecasts theoretically the internal forces and deformations in each construction stage. |
