Active Control of Buildings Subjected to Seismic Excitations

Meer over het boek

Focusing on earthquake resilience, this book explores advanced methods for controlling structural vibrations through active and passive energy dissipation devices and base isolation techniques. It introduces the Linear Quadratic Gaussian approach for designing active control systems, utilizing a State Space Model to analyze motion. The text mathematically interprets quadratic optimal theory for time-domain control algorithms, exemplified by an eight-storeyed building. It also determines optimal parameters for Active Tuned Mass Dampers (ATMD) and verifies system stability using Bode's and Nyquist criteria.
