abstract:
【Purposes】In this paper，a semi-active control method for structural vibration subject to near-field earthquakes is proposed. A neuro-fuzzy model is used to capture rate and temperature dependent nonlinear behavior of the SMA components of the hybrid device.【Methods】According to characteristics of near-field earthquakes，a non-
dominated genetic algorithm is employed to design a self-organizing fuzzy controller. To obtain optimal controllers for concurrent mitigation of displacement and acceleration responses
，fuzzy governing rules is tuned with the multi-objective heuristic optimization. Then，numerical simulation of a multi-story building is conducted to evaluate the performance of the hybrid device.【Findings】Results show that a self-centering variable friction device modulated with a fuzzy logic control strategy can effectively reduce structural deformations without increasing acceleration response during near-field earthquakes.
