Technical Note: Active and Semi-Active Strategies to Control Building Structures Under Large Earthquake Motion

Abstract

Structural Design, Architectural Engineering and Technology, Faculty of Architecture and the Built Environment, TU Delft, Delft, the NetherlandsAs of today, about 80 buildings equipped with active or semi-active devices for wind and earthquake-induced motion control have been reported. In the first part of this technical note, full-scale applications are reviewed to investigate whether large and severe earthquake levels were targeted as control objectives. In the second part, not yet implemented research studies (2011 -2014) are reviewed. The main conclusion is that strategies integrating control and structural design are the key for implementing large earthquake-target control devices in buildings.

Adaptive Vibration Control for an Active Mass Damper of a High-Rise Building

“…Thus, researchers have been paying more attention to active, semi-active and hybrid control methods recently [6], [7]. A review of control algorithms and optimal methods for active or semi-active devices before 2015 is presented in [8].…”

Optimal tuned direct adaptive controller for seismic protecting of structures

“…In recent years, the adequacy of active and semi-active control strategies in seismic protection of civil infrastructures has gained a great deal of attention from structural engineers (Askari et al, 2016; Bozorgvar and Zahrai, 2019; Braz-Cesar and Barros, 2018; Lu et al, 2019; Morales-Beltran and Paul, 2015; Oncu-Davas and Alhan, 2019; Younespour and Ghaffarzadeh, 2016). However, they are faced with many challenges in implementation and maintenance of the control systems.…”

H∞ control method for seismically excited building structures with time-delay

“…However, the actuators in semi-active systems do not directly apply the forces to the host structure. Indeed, they are used to control the damping properties of passive devices (Morales-Beltran and Paul, 2015; Saaed et al, 2015). In passive control methods, energy dissipation devices (absorbers) or isolator systems are usually used to attenuate the vibrations.…”

“…In spite of simple mechanisms and the cost efficiency of passive control methods, they have a limited capacity for suppression of seismic responses of structures. Such control systems are usually restricted for controlling only one dominant vibration mode of the structure and not for controlling other modes (Morales-Beltran and Paul, 2015; Saaed et al, 2015). Recent advances in the field of active vibration control have drastically changed traditional structural control concepts in civil engineering.…”
