摘要
综合了高层钢结构抗风抗震控制的发展。阐述了高层钢结构水平位移指标设计限值有待于进一步探讨。指出了现代控制技术对高层钢结构风振舒适度控制及外伸臂对框架 -核心筒结构体系水平位移指标控制的实现。阐明了TMD/TLD及主动控制对高层钢结构抗风抗震控制的现实意义及发展。
Several problems in development of wind and earthquake resistant control for tall steel structure are introduced in the paper.It is set forth that the limit value of lateral deflection is remained to be discussed further.It is pointed out that wind vibration comfort control on tall steel structure by using modern control technique and the lateral deflection control on the frame_core wall structure by using outriggers can be realized.The realistic meaning and the development of the TMD/TLD and active control are described for anti_wind and anti_seismic control of tall steel structure.
