| Abstract: |
| Concise closed-form solutions for random seismic responses of MDOF structures with Series Inerter Dampers(SID) were studied,and the effects of parameters and setting floor positions of SIDs on the seismic performance of building structures were analyzed.Firstly,the coupled seismic dynamic equations of a MDOF structure and a SID are established.Secondly,the quadratic decomposition method is used to derive a concise closed-form solution for the 0~2 order spectral moments of the absolute displacement of the structural nodes relative to the ground,interlayer displacement,and force of the SID.Finally,through an example,the correctness of the proposed solution was verified and the characteristics of the parameters of SID and the setting positions on the seismic performance of structures were studied.The result has shown that the influence of the SID on the interlayer displacement and absolute displacement of the top floor of structures is non-consistent;and the damper-setting strategy is economically feasible to set up a SID on floors with significant inter story displacement.The paper can provide a reference for the practical engineering application of inerter dampers. |
