The concept of vibration control has been spread throughout civil engineering field, while many of them are just imported from other field of technology such as control engineering and mechanical engineering. The main objective of this study is, therefore, to establish an original concept of controlfor vibration problems in civil engineering structures, that is, earthquake-, wind- and traffic-induced vibrations. Starting from characterizing their vibration and control problems including the extemal disturbances and the response evaluation, several types of control are studied to compare their control performance. The contents of the present study are summarized as follows.1.Control of Earthquake-lnduced Vibration : The design concept of control for elevated highway bridges were first discussed emphasizing on the importance of system design. Some active control scheme were then studied by taking into account of the characteristics of earthquake and structure.2.Control of Wind-Induced Vibration : The modeling of wind forces for the control design were first discussed and methods for evaluation of unsteady aerodynamic forces as well as nonstationary qusty wind forces were proposed. Several control schemes for flutterin long-span suspension bridges and for gust responses in high-rise buildings were also studied.3.Control of Traffic-Induced Vibration : The control of vehicle-induced vibration in highway bridges, that of traffic-induced noise in viaducts, and that of pedestrian-induced vibration in stress ribbon bridges were studied analytically as well as experimentally.4.An experimental system for studying control periormance has been established.

振动控制的概念已经在土木工程领域得到了广泛的应用，而许多振动控制的概念是从控制工程、机械工程等其他技术领域引入的。因此，本研究的主要目的是建立土木工程结构振动控制的原始概念，即地震、风和交通引起的振动。本文从描述其振动和控制问题入手，包括外部干扰和响应评估，研究了几种类型的控制，比较了它们的控制性能。主要研究内容如下：1.地震振动控制：首先讨论了高架公路桥梁地震振动控制的设计思想，强调了系统设计的重要性。2.风振控制：首先讨论了风振控制设计中的风荷载模型，提出了非定常气动力和非定常风荷载的计算方法。研究了大跨度悬索桥颤振和高层建筑阵风响应的控制方案。3.风振控制：公路桥梁车辆振动控制、高架桥交通噪声控制、和行人-对应力带桥的诱导振动进行了理论分析和实验研究。4.建立了一套研究控制性能的实验系统，确立了习
