Awareness of engineers in designing earthquake resistant building is arising nowadays. Many strategies have been developing by the researchers to get high performance in reducing earthquakeudresponses. Semi-active control strategy under earthquake loading is discussed in this report will beudapplied in three dimensionalthree-storeybuilding. In addition, the device has been added with magnetorheological fluid which will act as the liquid damper. Firstly is to fulfill all parameters in non-linear control strategy based on the building properties. Furthermore, theforce of the device in semi-active control strategy will be analyzed with MATLAB to get displacement response by comparing passive on, passive off control and Lyapunov method. The results of the simulation comparing the uncontrolled building result with semi-active control strategies (uncontrolled-passive off; uncontrolled-passive on; uncontrolled-Lyapunov method) show satisfactory result with displacement response reduction on the first floor are31.5%, 37.5% and 48.35%, the results on the second floor are 30.7%, 30.5% and 40.2% and the results on the third floor are 26.5%, 29.8% and 40%.ud
