Abstract
This paper is concerned with the design of linear matrix inequalities based optimal state-feedback controller design for seismic excited asymmetric structural systems having stiffness irregularities. A one storey, two way asymmetric structural system model is used to illustrate the effectiveness of approach through simulations. The modelled system has bi-lateral and rotational degrees of freedom. Frequency responses show the effectiveness of proposed controller by means of a decrease in the peak values of each resonance frequency. Moreover, the time domain simulation results, acquired by using real time-history data of San Francisco and El Centro Earthquakes also show that proposed controller is very effective in reducing vibration amplitudes of each direction by applicable control signals and guaranteeing the stability of closed loop system.
