Research Abstract |
This report is a summary of researches regarding to developments and estimations of structural response control system for impulsive ground motions. The contents are composed by following chapters : Chapter 1. Introduction, Chapter 2. The state-of-the-art of structural response control systems of buildings, Chapter 3. Evaluations of efficiency of control methods and control algorithms, Chapter 4. Development and estimations of structural response control system for impulsive ground motions, Chapter 5. Concluding remarks. In Chapter 2, many different kind of response control systems and control algorithms are classified and estimated for installing to structural response control system for impulsive ground motions. As constructions and investigations of response control system for impulsive ground motions are described in detail in Chapter 3 and 4. As stabilized non-linear control algorithms which are considered : installation feedforward controller, adaptation for non-linear properties of control system, and saturation problem for control forces, advanced adaptive model reference control method and quasi-optimizing control method are proposed and investigated in Chapter 3. Moreover, to develop structural response control system for impulsive ground motions, active airbag system and vertical shock-absorbed base-isolator system are proposed and estimated through numerical simulations and experimental tests in Chapter 4.
