Abstract |
In this study, in order to improve the performance of wall-type apartment RC coupling beams, a steel rod damper was applied to the coupling beams. The test variable was the number of steel rods, and a total of 4 test specimens were made. As a result of the material test of the steel rod, it was evaluated as conforming to KS standards. As a result of the test, it was evaluated that the stress was concentrated in the steel rod and not in the welded area of the steel rod and connection plate. The maximum strength was evaluated to increase linearly, but not proportionally, as the number of steel rod dampers increased.
