摘要
本文针对带粘滞阻尼器的高层建筑结构的随机风振响应和等效静态设计风载取值进行了系统研究。采用复模态理论解耦,并利用随机振动理论获得结构风振响应的解析式,建立了将结构分解为一系列等效单自由度体系的一般方法,继而利用等效单自由度体系随机风振响应的解析解,获得了带粘滞阻尼器的高层建筑结构基于现行规范Davenport谱随机风振响应的解析解,并给出算例,从而建立了非经典阻尼非对称的被动控制结构基于Davenport谱随机风振响应和风载取值的一般解析方法。
This paper makes a systematic research on the random wind vibration response of damper structure with viscous and the wind load value of equivalent static design in high rising buildings.In the research,decoupling is achieved by applying complex modal theory,and the analysis formula of structure wind vibration response is obtained with the random vibration theory,so as to get the methods to decompose the structure into a set of ESDOF and use the analytic solutions of random wind vibration response with ESDOF to get the analytic solutions of damper structure with viscous in high rising buildings based on the existing standard of Davenport spectrum.Through all the analysis,a set of analytic solutions are got to set up the non-classical,damping asymmetric passive control structure based on Davenport spectrum random wind vibration response and wind load value.
