| Research Abstract |
This report is a summary of researches regarding to developments and estimations of structural design under adaptive interfaces which are supported by response control techniques. The contents are composed by following chapters:
Chapter 1. Introduction,
Chapter 2. State-of-the-art of structural response control systems of buildings,
Chapter 3. Development and estimations of adaptive interfaces by introducing base-isolation systems,
Chapter 4. Development and estimations of adaptive interfaces by introducing passive control systems,
Chapter 5. Development and estimations of adaptive interfaces by introducing active control systems,
Chapter6. Concluding remarks,
In Chapter 2, much different kind of response control systems and control algorithms are classified and estimated for introducing adaptive interfaces based on structural response control techniques. And also, significant items to install structural response control system are investigated, namely, those are related to system identificat

ions, health monitoring and asseismic reinforcements. Installations and evaluations of adaptive interfaces for structural response control designs are described in detail in Chapter 3, 4 and 5. Portable installations of base-isolation systems are considered: Performance criterion's of friction bearing system, developments of shock absorbing device for impulsive ground motions and adaptiveness for asymmetry of upper constructions are considered and evaluated in Chapter 3. Adaptive evaluations of control performances for installations of passive control systems are considered: Generalized indicates based on ductility responses are introduced, and, passive damper system, generalized story-isolation system and hybrid type of those systems are examined and analyzed in Chapter 4. Applicability of control algorithms for installations of active Control systems are considered: QN control method, quasi-optimizing control method and model reference adaptive control method are proposed and investigated in Chapter 5.
