In this paper, the static characteristics of the T shaped frame with bended steel damper were investigated by cyclic loading test. The test parameters were the methods of connections and the number of dampers. Also, one stovy-one bay frame with the damper is veryfied. to have enough safety for seven earthquake by use of calculation of vespouse and limit Capacity. The test result showed that the compressive strength. The plastic deformation capacity of the damper is enough for seven earthquake ground motion.
