| Abstract: | In light of the construction difficulty of prestressed post-tensioned beam in Qingdao station renovation project,this paper designs the prestressed tensioning sequence,calculates the impacts of prestressed tension on beam deflection,and monitors the construction of prestressed post-tensioned beam in the field.The calculation results and monitoring data show that the post-tensioned beam construction scheme designed in the paper are safe and effective,which has guiding meaning for similar engineering construction in future. |
