Influence of Construction Procedures on the Liner and Stress of a PC Continuous Beam Bridge
During the construction of a bridge, the construction procedures may change from the originally designed procedures due to some reasons like the weather. In this paper, the influence of construction procedures on the liner and stress is investigated for a prestressed continuous beam bridge with three spans. Finite element analysis indicated that construction procedures have great impact on the liner control and they affect the middle span and side span differently. Although different sets of construction procedures cause different stress at corresponding construction stages after the cantilever construction is finished, they have no significant influence on the stress of the finally built bridge. Test data agreed with finite element analysis. It is thus the influence of construction procedures on bridge liner control should not be neglected.
