To reduce dynamic response of flexible structures with moving mass . there are passive , active and hybrid control methods. In this study, a 4 D. O. F. flexible and lightly damped structual frame model with and without these control devices are tested under earthquake ground motion generated by a shaking table. From the test with AMD ( active mass damper ) , the variable gain control is found to be effective for wide range of input intensity. And , the SOTMD ( self oscilating tuned mass damper ) which is one of the active TMD is newly developed. Then , the efficiency of 2 control algorisms is compared. It is found that the SOTMD with the most effective control algorisms needs only lO% of the AMD for the same level of dynamic response reduction. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
