Abstract [sv]

Rapporten diskuterar tidsberoende deformationer i anläggningskonstruktioner av armerad betong. Deformationerna kan bero på faktorer som uttorkning och fuktförhållanden (krympning) och/eller laster (krypning). I två bilagor ges en presentation av metoder för modellering (Bilaga 1) och av beräkning av spännkraftförluster i spännarmering (Bilaga 2). Områden för fortsatta studier rekommenderas.

Abstract [en]

The report discusses time-dependent deformations in civil engineering structures made of concrete. These deformations can depend on factors such as drying and moisture conditions (shrinkage) and/or loads (creep). Two appendices provide state-of- the-art reports  on modelling (Appendix 1) and on prestress losses in reinforcement (Appendix 2). Further studies are recommended.
