Study on PC Continuous Girder mechanical properties Based on Tendon Tensioning Pattern

prestressed concrete continuous box girder in China. With the change of condition in the construction site, the construction sequence of the bridge will be changed inevitable, so to adjust the tendon tension mode accordingly, which will cause the alteration of structural mechanics performance. The finite element analysis model of a continuous girder will be built to compare the difference with two tendon tension cases according to relevant pouring sequence. The related conclusions are obtained, so can help to provide beneficial reference for the similar engineering.
