Abstract [en]

Under the old calculation standards BBK the benefit was strength and various deformations according to standardized values ​​for the external circumstances. In the transition to the common eurocode in January 2011 these terms changed to specific values ​​of external circumstances and concrete strength for a more concrete custom calculation. This resulted in updated calculation software that have a problem with increased overbending with about doubled of the theoretical overbending. Tests to interpretation and calculation of shrinkage and creep conducted after a study of eurocode and a run through of the software PRE-stress basic knowledge to know how the program works and what values ​​affect deformations. A superficial examination of BBK conducted so comparisons between the old and new calculation standards were identified. The first results were varied and it was hard to notice a system. Following advice from another thesis localized values ​​that became more satisfying as calculated and given conditions. Expect the hike is a complex problem and given that manufacturers only provides a recommendation on how shrinkage and creep is allocated and eurocode can be interpreted in different ways, it becomes constructor individual interpretation and distribution that determines how large deformations PRE-Stress will present at calculations.
