| Abstract: | A three dimensional, nonlinear finite element analysis capability for analysis of cracked reinforced concrete nuclear containment vessels is described. A bilinear shear stress-shear strain model, based on experiments, is used to study the distribution of radial and tangential shear produced by horizontal seismic loading. Results show substantial redistribution of tangential shear, and significant increases in radial shear, peak bending stress, and vessel displacement, as compared to conventional linear analysis results. |
