REINFORCED-CONCRETE DIMENSIONING BASED ON NODAL FORCES CONSIDERING PLASTICITY

Abstract

The dimensioning design of the nuclear reactor building is based on the elastic analysis. But the real stress is different from the elastic situation. A rational dimensioning procedure that considered the stress redistribution due to plasticity is expected. A new approach for the dimensioning on Finite Element Method (FEM) was presented by Anderheggen and et. al in 1994. Its main idea is to impose dimensioning constraints not on the stress components by FEM, but directly on the nodal forces. This paper is about the investigation on the application of the procedure to the practical design.
