Fuzzy control of asymmetric plan buildings with active tuned mass damper considering soil-structure interaction

摘要

In recent decades, many researchers have conducted studies on structural control to improve the safety and serviceability of high-rise buildings or towers against earthquake and strong wind. Since most buildings have a sort of asymmetric plan they experience torsional effects when subjected to earthquake and subsequently the torsion would increase the structural response. Also, such buildings might be constructed on soft soil where the Soil-Structure Interaction (SSI) influence would be important.Thus in this paper, considering the SSI effect a mathematical model is presented to obtain the seismic performance of an irregular multi-story building having two Active Tuned Mass Dampers (ATMD) at center of mass on the top floor. The model is employed to investigate the seismic response of 10 and 15-story asymmetric plan buildings in different cases using fuzzy logic and LQR forces for those two ATMD. Moreover, two TMDs are used at the same location for result comparison. Obtained results demonstrated that using two ATMDs on the top floor would reduce induced structural response in the 10 and 15-story buildings even in those on soft soils.
