The study focuses on the seismic vibration control of non-structural elements (NSEs) placed on 5 storied buildings installed with various structural control systems such as passive linear viscous dampers (LVDs), non-linear viscous dampers (NLVDs), and visco elastic dampers (VEDs). The displacement and acceleration responses for the multi-story building are obtained by mathematically solving the governing equations of motion using the state space approach. Optimum parameters for the dampers are derived from the numerical study. To investigate the effectiveness of different dampers in the symmetric building, a comparative study between the controlled response and the corresponding uncontrolled response is carried out. It is shown that the proper implementation of different dampers along with appropriate structural parameters reduces the earthquake-induced deformations significantly for NSEs. Also, the use of floor absolute acceleration response spectra is recommended as the prime demand parameter on non-structural elements to capture the true nonstructural seismic demand in a better way.
