Multi-Axis Loading Test on RC Shear WallsOverview and Outline of Two Directional Horizontal Loading Test

摘要

Nuclear Power Engineering Corporation (NUPEC) has been conducting a project entitled "Model Tests of Multi-AxisrnLoading on RC Shear Walls" to clarify the elasto-plastic characteristics of an RC seismic shear wall, and to develop a methodrnof evaluating restoring force characteristics under multi-directional seismic loading conditions. This paper provides arnsummary of the two-directional horizontal loading test, which was performed as a part of the project from fiscal 1999 to 2001.rnShear wall specimens of box type and cylinder type were tested by applying orthogonal horizontal loads in the specimens XYrndirections. The load applied in each X and Y direction for three box type specimens forms patterns of rectangular, crossrnand diagonal cross. For the cylindrical shear wall, a rectangular form of load was applied in the X-Y plane.
