Active-Passive Decentralized H∞ Control for Adjacent Buildings Under Seismic Excitation
نویسندگان
چکیده
In this paper, a control strategy to reduce the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines passive linking elements with an active decentralized H∞ control system. The overall active-passive control system admits decentralized design and operation, and achieves an excellent vibrational reduction when the active control system works; in case of a full or partial failure of the active control system, a remarkable reduction in the vibrational response is guaranteed by the passive linking elements. For adjacent buildings that require different levels of seismic protection, the implementation of an activeH∞ control system in just one of the buildings is also considered. The main ideas are presented by means of a simplified two-building model. Numerical simulations have been carried out to assess the performance of the proposed methodology with promising results.

Control strategies for large-scale structural systems: high-raise buildings and multi-building systems
This work presents an overview of some recent developments made by the authors in the field of vibrational control of largescale structural systems subject to seismic excitations. The structural systems under consideration are classified in two broad categories: (i) high-rise buildings, and (ii) multi-building systems. When dealing with high-rise buildings, the inclusion principle can be used a...

Seismic pounding occurs as a result of lateral vibration and insufficient separation distance between two adjacent structures during earthquake excitation. This research aims to evaluate the stochastic behavior of adjacent structures with equal heights under earthquake-induced pounding. For this purpose, many stochastic analyses through comprehensive numerical simulations are carried out. About...

متن کاملExperiments on Coupled Technique for Adjacent Similar Buildings
Increasing the population, urbanization has led to the rapid construction of buildings. Due to space constraints and an increase in land cost, these buildings are built too close to each other and can cause damage under dynamic actions such as earthquakes. A new technique, known as Structural coupling, has been developed recently, has found very effective in dissipating the dispersive vibration...
