Stability Analysis of High-Pile and high-pier Considering Initial Pier Deviation

Based on the high-pile and high-pier bridge of Qianhuang Expressway, eigenvalue buckling analysis is carried out by establishing three-dimensional finite element models three different types types, corresponding structural nonlinear loads under initial pier deviations are calculated. The calculation results show that less than elastic loads. stability column continuous better simple supported bridge, plate other two high-piers. In addition, load decreases with increase horizontal displacement, indicating top offset not conducive to structure.
