摘要:

为推动黏滞惯质阻尼器(VIMD)在高层基础隔震结构中的工程应用,以20层隔震钢结构模型为研究对象,首先,探讨VIMD的惯质对结构自振周期的影响;然后,从太平洋地震工程研究中心选取10条实际地震动并进行调幅使其匹配目标设计反应谱,研究VIMD对结构地震响应的控制特征及减震效果;最后,基于达文波特脉动风速谱,采用谱表示法生成10条随机脉动风速时程,研究VIMD对结构风振响应的控制特征及减振效果。结果表明:VIMD可延长该高层基础隔震结构的自振周期,且主要体现在前6阶。在地震激励作用下,VIMD对高层基础隔震结构隔震层相对位移响应的减震效果与黏滞阻尼器(VD)相当,但其对上部结构响应的减震率较VD可提升19.5%~24.5%。在风荷载作用下,VIMD和VD对高层基础隔震结构响应控制能力基本相同。

Abstract:

To promote the engineering application of VIMD in high-rise base-isolated structures, a 20-story base-isolated steel structure model was considered. First, the influence of the VIMD's inertance on the structure's natural periods was investigated. Then, 10 real ground motion records were selected from the Pacific Earthquake Engineering Research Center database and were scaled to match the target design response spectrum. The control characteristics and seismic mitigation effects of VIMD on the structural response were studied. Finally, based on the Davenport fluctuating wind speed spectrum, the spectral representation method was used to generate 10 stochastic fluctuating wind speed time histories. The control characteristics and wind-induced vibration mitigation effects of VIMD on the structural response were studied. The results indicate that VIMD can further extend the natural periods of the high-rise base-isolated structure, mainly in the first six modes. Under seismic excitations, the control effectiveness of VIMD on the relative displacement response of the isolation layer is comparable to that of Viscous Dampers (VD). However, the vibration mitigation ratios of VIMD for the response of the superstructure is improved by 19.5%-24.5% compared with that of VD. Under wind loads, VIMD and VD have basically the same response control capabilities for the high-rise base-isolated structure.

Key words: viscous inertial mass damper(VIMD), high-rise base-isolated structure, natural period, seismic performance, wind resistance performance
