SEISMIC RESPONSE CHARACTERISTICS BASED ON ENERGY BALANCE OF RESPONSE-CONTROLLED AND LINKED STRUCTURAL SYSTEM OF OVER-TRACK BUILDING

As a simple damage control structure to apply to over-track buildings with many restrictions on design and construction, response-controlled and linked structural system is effective. In order to make fixed quantity evaluation of the response reduction effective, the validity of the response evaluation by energy balance can be verified by lumped mass system model. Large effect of energy absorption is provided by the combination that is off the most suitable setting in linear range. The effect becomes small in non-linear range, but also large energy absorption is provided by using together with the vibration system including internal damping mechanism.
