Abstract

In the present paper, the effect of controllability and control system stability was investigated. For this purpose, three, six, ten, and twenty-one-story structural models equipped with Chevron braces, viscous fluid dampers, and active regulators were selected in uncontrolled, passive-controlled, and hybrid-controlled structures. In order to stabilize the hybrid control system, the linear quadratic regulator algorithm was utilized to calculate the state feedback gain matrix and actuator response. Broadly, the results revealed that if a sufficient number of braces, dampers, and actuators are utilized in the stabilized hybrid control system, the response of braces and dampers is converged and the seismic displacement of braces and floors is decreased properly.
