The ultimate pressure capacity of a prestressed concrete containment building according to the concrete models

The research on the ultimate capacity and integrity of containment buildings has been performed all over the world since the late 1980's, because the containment building has a role of a radiation shield when a severe accident occurs. The containment building is constructed with a complex material such as concrete, reinforcement, liner plates, and tendons. Therefore it is difficult to predict the response of containment structures with numerical methods because of the complex behaviors after a cracking of the concrete, and the uncertainties in the properties of the concrete. The purpose of this paper is to compare the ultimate pressures of a prestressed concrete containment according to the concrete models in the computer code ABAQUS
