Abstract: The research program will develop regulatory requirements for SC walls in nuclear structures, including numerical models, acceptance criteria and prescriptive details, with explicit consideration of beyond design basis loadings and the coupling of in-plane and out-of-plane responses. Large-scale physical tests will be executed in the Bowen Laboratory at Purdue University. The project builds on prior work by the PIs developing regulatory guidance for the US Nuclear Regulatory Commission (Whittaker) and design guidance for the American Institute of Steel Construction (Appendix N9 to AISC N690 on SC walls; Varma), the American Concrete Institute (ACI 349; Whittaker) and American Society of Civil Engineers (ASCE 4/43 and Nuclear Standards Committee; Whittaker). The researchers will effectively leverage their experimental and analytical/numerical studies on SC walls for the US National Science Foundation, the US Department of Energy, and industrial sponsors willing to share proprietary data. Relevant studies, models and experimental data on low aspect ratio RC walls, assembled as part of Whittaker’s NSF-funded NEESR study, will be utilized. Robust numerical models for analysis, acceptance criteria for design, and prescriptive rules for detailing will be developed. The numerical models for in-plane and out-of-plane response will be based on analysis of a) models proposed to date by the PIs and others, and b) SC wall test data available to the PIs and test data generated in the proposed project. Acceptance criteria for design and prescriptive rules for detailing will be proposed, consistent with formats used in AISC N690 and ACI 349, and will be based on test data and results of numerical simulations.
