Prestressed Concrete Silo

I am working on silo design to present in a seminar. Normal pressure on the silo wall is to high and need a prestress (post tension). Design is done by using Eurocode. My question is about post tensioning force in combination. According to eurocode-2, prestressed force can be accepted as permanent actions.
