Seismic behavior of SC Walls has tremendous impact to the seismic performance of nuclear power plants. Seismic Probabilistic Risk Assessment (SPRA) has been well-recognized as the most comprehensive and complete methodology to assess seismic risk of nuclear power plants. SPRA requires fragility data of structural and non-structural components in NPPs. Seismic vulnerability analysis on SC walls becomes essential to improve the understanding on seismic behavior of SC walls and to aid in the development of fragility curves for SC walls. 　　In this study, the initial stiffness and in-plane later-force strength of flexure-critical and flexure-shear-combined SC walls were studied using 1) basic principles (i.e., equilibrium, compatibility, and constitutive law of steel and concrete), 2) section-analysis software XTRACT, and 3) FEM program ABAQUS. The results of the three procedures were compared with experimental data in literatures. A plan for cyclic loading tests of four SC walls is also presented. The tests will be conducted in late 2014 and the results will be used to validate the conclusions of this study.
