ABSTRACT
The limit state analysis is proposed in this paper. The analysis takes into consideration two types of dome namely, spherical and elliptical, which are generally associated with the barrel wall. Constitutive equations are developed in which a provision is made for tendon geometry, loads and losses due to prestressing tendons. Stresses are computed for the domes and the barrel wall using a specially developed program (HAYA). A separate analysis is carried out for the discontinuity at the base of the barrel wall. Boundary conditions are adjusted so as to create flexibility for the dome and wall to interact. The analysis is applied to both Sizewell B and Bellefonte vessels. Only Bellefonte vessel results are reported.
