摘要
为进一步对巨-子型有控结构的动力特性进行分析,采用AR模型方法,首先对考虑空间相关性影响的水平脉动风速作了模拟。为弥补频域分析的缺陷,采用时程分析法求解巨-子型有控结构的风振响应,结果表明:巨-子型有控结构是一种有效的结构形式,与一般巨型框架结构相比能显著降低结构的风振响应,具有极大的工程应用前景。
In order to investigate the dynamic characteristics of mega-sub structure under random wind loads,the auto-regressive model is applied to simulate pulse wind velocity,and the time history of pulse wind load varying along with the space positions has been concisely imitated.Based on time-domain instead of frequency domain which can't reflect the response directly,a new mega-sub controlled structure with additional columns is calculated.The result indicates that the new controlled mega-sub structure can reduce the wind response evidently compared with normal mega-frame structures,which may be a new type of promising system in practical project.
