This paper presents the method of semi-active control design considered with characteristic of earthquake motion and sensors placement for 4-story base isolated structure with 4 oil dampers whose damping coefficient can be changed at two steps. This method uses information of both sensor placement and structural response in the control design at the same time. We proposed the optimal sensor placement using fewer sensors compared with conventional control design method. The forgetting genetic algorithm is applied to multi-layered neural network and this algorithm is used not only to adjust the neural network parameters but also to forget the weak neural network in learning. This proposed method is effective to simplify the neural network, and as the results of simulation, the input information is made a choice. We can realize reduction of the structural response to use fewer sensors and decide the sensor placement under two different earthquake motions by the proposed control design method.
