Özet
In this study, active controlled ten-story structures including soil-structure interaction (SSI) are investigated under different type of ground motions (near-fault and far ground motions) defined in FEMA P-695 to show the effect of earthquake records on SSI. In structures, where active tendons are located on each floor, the proportional-integral-derivative (PID) controllers are used. Optimum tuning of PID control parameters are calculated with the teaching-learning-based algorithm (TLBO) and harmony search algorithms (HSA) which are commonly used metaheuristic algorithms. The properties such as swaying and rocking stiffness and damping of dense and soft soils were added to the foundation of the structures to consider the soil-structure interaction. The changes of structural reactions in two types of earthquake records are examined by decreasing or increasing these properties of soils by 10 and 20%. As a result, reduction and enhancement of properties of soft soil in structural responses are changed significantly, while these values are not changed much for dense soil. © 2021, Springer Nature Switzerland AG.
