Application of the seismic isolation and seismic response control technologies in order to ensure the required performance for the civil engineering structures is investigated. The analysis of performance requirement to resist the level-2 earthquakes and the study on the performance of structures with the application of seismic isolation and seismic response control technologies are conducted, and the engineering feasibility and issues in those technologies are studied. The research has been conducted in mainly the following topics:(1) Verification of semi-active seismic response control of adjacent structures using the variable damper system. Three types of control schemes, namely the conventional viscous damping control, linear quadratic control method, as well as the newly developed pseudo-negative stiffness control methods are compared, and the full-scale test results show that the proposed pseudo-negative stiffness control method gives the best control performance.(2) The experimental performance evaluation methods for the seismic dampers are investigated, and the effectiveness of the Inertia Force Driven Damper Loading Test system is investigated.(3) The use of friction-type bearing in the seismic isolation to bridge structures and the modeling of this type of isolation devices to predict the seismic response of isolated bridge structures are investigated, with the emphasis of establishing rational design methods for this type of isolation bearings.(4) Seismic retrofit of existing long-span bridges with seismic isolation and seismic response control technologies are investigated, and some case studies show that the improvement of seismic performance can be effectively achieved by using these technologies.

地震隔离和地震反应控制技术的应用，以确保研究土木工程结构所需的性能。通过应用地震隔离和地震反应控制技术的应用，对抵抗2级地震的性能需求进行分析，并研究了这些技术的工程可行性和问题。该研究主要在以下主题中进行：（1）使用可变的阻尼器系统对相邻结构的半活性地震反应控制进行验证。比较了三种类型的控制方案，即比较常规的粘性阻尼控制，线性二次控制方法以及新开发的伪阴性僵硬控制方法，并且全尺度的测试结果表明，提出的拟议的假性僵硬控制方法具有最佳的效率。研究了驱动的阻尼器加载测试系统。（3）在地震隔离中使用摩擦型轴承在桥结构中的使用以及这种类型的隔离设备的建模来预测隔离桥结构的地震反应，并强调建立这种类型的隔离式隔离轴承的隔离式响应方法（4）隔离式隔离轴承。研究了技术，一些案例研究表明，使用这些技术可以有效地实现地震性能的改善。
