Non-linear modeling techniques of prestressedconcrete construction : The nuclear containmentvessel of Forsmark 3 (English)
Abstract [en]

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.

Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization. For low pressurizations the results differ from thereference simulation. The reason is most likely the lack of friction.

The model with friction included cannot give correct results since the simulations failto represent the true friction between tendons and concrete. However the model issimpler and will probably in a functioning state give more accurate results comparedto the frictionless model.
