In order to comprehend the elasto-plastic behavior of RC box type shear wall subjected to diagonal load, reversed cyclic loading test has been carried out using 8 test specimens where loading angles and shear span ratio were set as test parameters. From the test results, it was observed that loading angles affected the maximum load and overall deformation, and they tended to be larger as the loading angle was close to 45 degree. Based on the conventional methodology to calculate restoring force characteristics of nuclear power buildings, we proposed an evaluation method taking into account the effect of diagonal loading for shear and bending components. Comparing with calculated results using proposed method and the test results, calculated results coincided well with the test results, and applicability of the proposed method was confirmed.
