Abstract
All fuzzy logic controller specifications and active tuned mass damper (ATMD) parameters are simultaneously optimized under seven pulse-type near-fault earthquake records. The last story's peak displacement and the maximum inter-story drift are separate objective functions. The controller is installed on the roof of a 15-story building, and its characteristics are determined by a 3-dimensional finite element model of a real structure. Adopting a simple model, soil-structure interaction effects are investigated. Geotechnical tests of the site soil are used to determine soil characteristics. A general-purpose center of mass optimization algorithm is established to tackle the optimization problem. The algorithm results are compared with those of two popular optimization algorithms. An ensemble of twenty-four pulse-type ground motions is utilized to evaluate and validate the proposed controller. Optimal results are compared and discussed for the two objective functions, where interpreting numerical results may contain practical information about excitations and the structure.
