Analysis of the Sandia one-sixth-scale reinforced concrete containment model: Interim report
This report describes part of Phase 3 of the project ''Methods for Ultimate Load Analysis of Concrete Containments.'' As part of the overall objectives to develop a qualified analysis methodology for concrete containment structures, this phase of the research utilizes analytical techniques which have been developed and verified in Phases 1 and 2 to perform comprehensive detailed analyses of the Sandia 1:6 scale reinforced containment model. The EPRI-sponsored finite element code, ABAQUS-EPGEN, and the concrete constitutive model developed previously are the analysis tools used in this research. A comprehensive set of a pre-test predictions were developed in 1986 and 1987 including a series of 2D analyses to identify critical regions, and a number of 3D local analyses to characterize 3D response components. These predictions were compiled and reported to EPRI prior to the test but have remained unpublished until their inclusion in the current report. This material is included here as an Appendix; the predictions based on this work successfully predicted the leakage pressure and many of the liner tearing locations that occurred in the test. The main report compares the pretest calculations to the test results, and it describes several post-test analyses, including axisymmetric analyses to investigate basemat uplift behavior, and the effect of changing concrete tensile strength and a 3D local analysis that studies the behavior at the largest liner tear that occurred. Conclusions of the paper access the analytical methodology in light of the test results. 20 refs., 59 figs.
