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.
