REPEATED DEFORMATION BEHAVIOR AND LOW CYCLE FATIGUE CHARACTERISTICS OF U-SHAPED STEEL DEVICE APPLIED TO SHEAR WALL FOR STEEL INDUSTRIALIZED HOUSE

We proposed U-shaped steel device applied to shear wall for steel industrialized houses. In the previous report, the influence of the shape factor of the device on the mechanical performance was clarified. However, the fatigue performance evaluation method for U-shaped devices has not been established. Therefore, in order to establish a fatigue performance evaluation method, the fatigue performance of the device was experimentally verified. In addition, the repeated deformation behavior is analyzed using analysis. The relationship between the deformation behavior and the difference in curvature amplitude caused by the difference in loading amplitude and the fatigue performance will be considered.
