Abstract

Earthquakes are responsible for the destruction and severe damage to buildings and structures because of their peak accelerations. The objective of this paper is to design controllers for buildings which are modeled using nonlinear models and subjected to earthquakes. The designed nonlinear controllers ought to be able to significantly reduce the floor displacements when a building is subjected to earthquakes. The nonlinear controllers are designed for buildings which are subject to earthquakes are based on the Sliding Mode Control (SMC) technique. The designed controllers are simulated using the Matlab/Simulink software. The simulation results indicate that the proposed controllers work well.
