Axisymmetric Modeling of Prestressing Tendons of the Nuclear Containment Building Dome
원전 격납건물 돔의 축대칭 텐던 모델링 기법
- Published : 2004.05.01
Abstract
Prestressing tendons of the nuclear containment building dome are arranged in a non-axisymmetric manner. However, simple axisymmetric modeling of the containment building is often employed to estimate the structural behavior for, e.g. the ultimate pressure, which requires the axisymmetric approximation of the actual tendon arrangements of the dome. A procedure is proposed that can devise the actual 3-dimensional tendon stiffness and prestressing effect into the axisymmetric model. A numerical example of the CANDU type is presented to verify the procedure and to estimate the amount of approximation.
