摘要
为研究高耸结构TMD附加有效阻尼比计算方法的适用性,建立了设置TMD和不设置TMD的某高耸结构ETABS模型,采用规范法、时变法、自由衰减法分别计算了TMD的附加有效阻尼比,并开展了振动台试验,根据试验结果得到了TMD的附加有效阻尼比。研究结果表明:评估高耸结构TMD的附加有效阻尼比时,计算方法可以采用时变法、自由衰减法;振动台试验法得到的附加有效阻尼比较为可靠,建议开展振动台试验进行验证。
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.
