Seismic Response on Soil–Structure Interaction of Asymmetric Plan Buildings with Active Tuned Mass Dampers

Abstract

Many studies on structural control have been done in recent decades to enhance the safety and serviceability of high-rise structures or towers against earthquakes and severe winds. Because most structures have an unbalanced layout, when they are exposed to an earthquake, they undergo torsion effects, which exacerbate the structural reaction. Also, such structures might be built on soft soil, where the influence of the Soil–Structure Interaction (SSI) would be significant. Thus, taking into account the SSI effect, a mathematical model is developed in this study to determine the seismic performance of an irregular multi-story structure with Active Tuned Mass Dampers (ATMDs) at the top floor. The results were produced utilizing MATLAB/SIMULINK software using the proposed hybrid Shallow Neural Network (SNN) technology and Shuffled Shepherd Optimization (SSO). The seismic response of 40-story asymmetric project buildings is studied using this model. The findings showed that using ATMDs on the higher floors of 40-story structures on soft soil reduced the produced structural reflexes. When compared to the Particle Swarm Optimization (PSO) and Ant Lion Optimization (ALO) algorithms, the suggested technique outperforms them both.
