Analysis of Shrinkage and Creep Effect on Improved Truss Composite Arch Bridge

Abstract:

In order to study the shrinkage and creep effect on improved truss composite arch bridge , this paper analyzed and compared different parameters' influence on the truss composite arch bridge by changing parameters such as shrinkage days, the age of loading, computation theory and diagonal web member forms. It was based on Shiqiaohe bridge, the result showed that shrinkage days and the age of loading were the key parameters; the longer the shrinkage days makes the effects of creep bigger; the longer the age of loading makes the effects of creep smaller. The effect of shrinkage of rigid diagonal web member was larger than that of cables, the applied computation theory has little influence to shrinkage and creep effect on truss composite arch bridge.
