Inner force analysis of curved prestressed concrete rigid frame bridge with long-span and high piers

GUO Fan,YANG Yongqing,JIA Shuyang (School of Civil Engineering,Southwest Jiaotong University,Chengdu 610031,China)  
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 suggestions for design and construction of curved frame bridge to a certain extent.
