Seismic control of buildings with active tuned mass damper through interval type-2 fuzzy logic controller including soil–structure interaction

Abstract

This paper presents the application of interval type-2 fuzzy logic controller (IT2FLC) in ATMD for the response control of a building considering soil–structure interaction (SSI). One of the main constraints of the current fuzzy systems is their inability to consider uncertainty in fuzzy rules. Interval type-2 fuzzy systems have the ability to handle this deficiency. It also takes into account uncertainty in loading and structural behavior. To evaluate the influence of soil types on the behavior of structure, an 11-story shear building is used. This structure has been analyzed under the earthquake excitations recommended by the International Association of structural control (IASC) committee. The uncontrolled and controlled responses of structure with ATMD through IT2FLC are calculated with and without SSI effects. Numerical results indicate that SSI would significantly affect the structural response of the building. It is also found that when a structure is built on soft soil sites, the effectiveness of ATMD with IT2FLC in the case of suppressing the structural response is increased.
