Semi-active control of building structures using a neuro-fuzzy controller with acceleration feedback. In 6th International Conference on Mechanics and Materials in Design. Azores, Portugal. p. 1177-1190. ISBN 978-989-98832-3-9978-989-98832-3-9http://hdl.handle.net/10198/17502The present paper investigates the effectiveness of a neuro-fuzzy controller to reduce the response of building structures subjected to seismic excitations. The proposed controller was developed using an Adaptive Neuro-Fuzzy Inference System (ANFIS) to train a fuzzy logic system. In this case, floor acceleration measurements are used to compute the desired control signal to command a MR damper. A numerical example involving a three degrees of freedom building structure excited by the El Centro earthquake is presented to demonstrate the effectiveness of the proposed semi-active control system in reducing the response under seismic loading. A comparison between uncontrolled and controlled structural responses are used to validate the performance and efficiency of the proposed semi-active controller.engStructural controlSemi-active controlNeuro-fuzzyMR dampersconference object
