It is based on the premise that if the desired control force and the future earthquake excitations have the similar frequency contents, it is likely that the control force of the system will be most effective. Based on that premise, it is assumed that the shape of the PSDF of the control force is the same as that of the PSDF of ground motion representing the future earthquake. This assumption makes also the control problem to be site specific. The control scheme developed has the advantage that it can consider limited number of feedback measurements, time delay effect, and target reduction in response. The ANN control scheme requires feedback responses (displacement, velocity and acceleration), ground excitation and a target percentage reduction as inputs to the ANN. The output of the ANN is the time history of control force. A ten-story building frame is taken as an illustrative example. Feedback responses are taken from 1st, 5th and 10th stroys of the frame. The control is affected by a single control force applied at the top of the building frame with AMD. The results of the study show that (i) the control scheme is very effective in controlling the response of the building frame for excitations under El Centro earthquake taken as an unknown problem; (ii) The peak control force required to obtain a significant percentage reduction in response is not very large.; and (iii) Time delay (of the order of 2Δt; Δt time step interval) does not significantly deteriorate the performance of control scheme.
