Abstract
The second phase of this research focuses on the dynamic behavior of a three-story structural model subjected to vibration analysis, expanding upon the initial phase without dampers. Two scaled 1:10 prototypes have been developed; one constructed with 3D-printed polymeric floors and the other with plywood decks, each framed with steel members and designed to represent mid-rise building behavior.
A newly acquired shake table has been installed and integrated with data acquisition components to enable controlled base excitation and real-time response monitoring. The experimental setup now combines the shake table, waveform generator, accelerometers, and vibrometers to record the building’s acceleration and displacement under varying input motions.
One of the models incorporates fluid viscous dampers positioned diagonally between floors to improve lateral stability and energy dissipation. The vibration tests evaluate the influence of these dampers on frequency response, amplitude reduction, and mode shape variation. Scaling relations for acceleration and frequency have been refined to align the laboratory data with real structural conditions.
The compact shake table platform allows interchangeable model mounting for future comparative studies. Overall, this ongoing investigation aims to optimize damping configurations and viscoelastic modeling approaches to advance resilient structural design for buildings in seismically active environments.
