Prestressing Losses in Sungular Struture Areas and the Cross Section Warping Effect ? Full Scale Test

Popis výsledku v původním jazyce

Reliable design of prestressed concrete elements and structures have to be based on the accurate determination of prestressing force (including losses and their time development) to satisfy stress as well as deformation limits. Commonly used obsolete computational routines and methods neglect or incorrectly describe real effects and the results obtained by analysis based on these methods are thus necessarily misleading ? great differences from results obtained by measurements on real structures have been found. After 50 years of precast concrete members used for Vienna metro is possible to compare real outputs from full scale test with theory for prestressing force determination include the new approaches for real 3D behaviour.
