The NONSAP-C finite element code is described and its application to the nonlinear structural analysis of three-dimensional concrete containments under static, dynamic, and long-term loadings is reviewed. Features of this code that allow for easy application to realistic concrete structural problems are discussed, along with the various material models used to represent plain and reinforced concrete, for both time-dependent and time-independent behavior. Applications of the code to analysis of conventional reinforced concrete structures and to the structural analysis of prestressed concrete reactor vessels (PCRVs) and PCRV models are illustrated. Comparisons of the code predictions with previous numerical solutions to these problems or to experimental data are made. Input instructions for the NONSAP-C code are described.
