Description
Summary:The paper explores various control strategies proposed by researchers from decades ago in controlling the building structural system. It focuses on hybrid mass dampers used by many researchers in their previous work because the implementation of this device needs an excellent control strategy to provide a better performance in suppressing building vibration. The suitable choice of control strategy in structural control is important in giving the best structure response to withstand an earthquake or strong wind. Based on previous structure and control strategies, a simulation for a two-storey building structure system equipped with a hybrid mass damper at the top building has been conducted. Fuzzy logic controller (FLC), Sliding mode controller (SMC) and fuzzy sliding mode controller (FSMC) are used to suppress the building structure vibration during an earthquake by giving input from seismic excitation taken from El Centro earthquake. The simulation result shows that FSMC technique provides better performance compared to FLC and SMC in suppressing the building vibration based on the displacement response and frequency response. This paper concludes with the problems left and recommendations for structural control improvement.
