A viscoelastic model for the long-term deflection of segmental prestressed box girders [PDF]

, 2017
Most of segmental prestressed concrete box girders exhibit excessive multidecade deflections unforeseeable by past and current design codes. To investigate such a behavior, mainly caused by creep and shrinkage phenomena, an effective finite element (FE ...
