| Abstract: | Based on introducing the structural characteristics of curved prestressed concrete rigid frame bridge with long-span and high piers,analysis the effect on stress and displacement which are caused by beam deadweight,prestress,shrinkage and creep of the concrete,and horizontal curve.Combining with an engineering project,build a finite element model to analysis the regularity of stress and displacement,then the structural spatial behaviors of this type bridge were investigated.The study may provide some sugges... |
