Numerical Simulation and Analysis of Stabilization of Concrete-filled-steel Tube Arch Bridge in Construction

ZHENG Jian-rong,WANG Shu-mei (Fujian Agriculture and Forestry University,Fuzhou 350002) YUAN An-hua (Fuzhou Planning & Design Research Institute,Fuzhou 350002)  
3-D structural model was established with current finite element software,and the force applying in construction was analyzed.Compared with detected data,it shows that its correlation is good,the effectiveness of the model is reliable.The models is used to analyze the stability of the construction.The results indicate that the stability increase with the rigidity increase but decreases as the weight gets up.The elastic lateral buckling occurs during the construction in the first place.
