Controlled Seismic Response Engineering
Description
This book presents an alternative framework for seismic response control based on geo-coupled structural interaction and controlled seismic energy redistribution. The proposed system combines a prestressed, ground-anchored inner core with an elastic external frame, enabling controlled energy dissipation, reduction of relative displacement, and transfer of inertial demand into the surrounding geomass. The approach integrates theoretical mechanics, numerical simulation, and experimental investigation to formulate a coherent design philosophy aimed at reducing seismic damage while maintaining structural integrity. Emphasis is placed on physical transparency, reproducibility of simulations, and practical relevance for contemporary seismic engineering.
