In order to study the applicability of the calculation method of additional effective damping ratio of TMD in high-rise structures,the ETABS models of a high-rise structure with TMD and without TMD were established.The additional effective damping ratio of TMD was calculated using the specification method,the time-varying method,and the free attenuation method,respectively.The shaking table test was carried out,and the additional effective damping ratio of TMD was obtained according to the test results.The research results show that:Time varying method and free attenuation method can be used to evaluate the additional effective damping ratio of a high-rise structure with TMD;The additional effective damping ratio obtained by the shaking table test method is reliable,and it is recommended to carry out shaking table test to verify it.
