Strengthening methods of prestressed concrete box girder bridges.

open access: yes, 2019
In Lithuania and other European countries exploitation of prestressed concrete box girder bridges, built by cantilever method in 1965-1985, is a big problem. Due to defects risen from bridge exploitation bridge deck’s deflection is constantly increasing.

A Study on Rational Pre-Tensioning Schemes for 60 m Prefabricated Railway Box Girders Considering Steel Formwork Constraints

open access: yesBuildings
Early-age cracking is a common issue in the prefabrication of large-scale box girders, and the application of pre-tensioning techniques to introduce pre-compressive stress is an effective measure to mitigate such cracking.
