Description
| - The long-term deflections of cast-in-place segmental bridges constructed using the cantilever method are often larger than the deflections expected in the design. A detailed structural analysis and monitoring of these types of bridges has therefore become a matter of interest. The paper gives a comprehensive analysis of phenomena that can conspire to cause long-span prestressed concrete bridges to deflect more than predicted. The analysis is based on a parametric study and long-term monitoring of the behaviour of a Motorway Bridge across the Vltava River in the Czech Republic. To reveal and quantify possible reasons for excessive bridge deflections, a detailed time-dependent analysis was carried out. The results of the study were compared with in-situ measurements that have been regularly carried out since the very early stage of construction. Theoretical values of the increments of deflections, prestressing forces and concrete strains were compared with the measurements.
