Abstract |
In this study, the hysteretic behavior of a steel rod damper designed for application in coupling beams was evaluated based on findings from previous research. The steel rod damper features detailing to prevent lateral deformation, and four specimens were manufactured with varying numbers of steel rods. Loading was applied in accordance with inter-story drift ratios. The experimental results indicated that as the number of steel bars in the damper increased, the maximum strength also increased, but not in direct proportion to the number of dampers. In terms of the failure mode, the damper functioned effectively up to a displacement of 73 mm before reaching final failure.
