Nuclear Power Engineering Corporation (NUPEC) conducted a shaking table test for reinforced concrete seismic shear wall using the shaking table of Public Works Research Institute of Japan as for a part of the project of 'Model Tests of Multi-Axis Loading on RC Shear Walls'. The shapes of the specimens are box type wall and cylindrical wall. The dimensions of the box type RC shear wall are 1.5m by 1.5m in plan and 1.0m in height. The dimensions of the cylindrical shear wall are 1.9m in diameter and 1.0m in height. The tests were performed by applying two horizontal motions (X, Y) and vertical motion (Z) simultaneously. The tests consist of eight or nine step testing. In each step, the applied accelerations are increased step by steps. Every wall face of each specimen reached failure simultaneously in the final excitation step. In this paper, results of three-dimensional FEM analyses which simulate test results are discussed. A shear wall were modelled four-node layered shell elements considering out-of-plane shear deformation. The upper slab, base slab and added weight were modelled with shell elements. Four-direction crack model is used with two orthogonal coordinates corresponding to non-orthogonal cracks. NUPEC model developed by the Element Test in 'Model Tests of Multi-Axis Loading on RC Shear Walls' was used for shear transfer mechanism along shear crack surface. Material properties of concrete were derived from material test results conducted at the test day. Damping factor was estimated from the test results.
