Seismic Performance Evaluation of 5 Different Wireway-pulley System Subjected to Shaking Table Test

This paper presents the results of an experimental seismic investigation performed on prototypes made of a pulley-wireway system with four different boundary conditions and an existing lighting structure support, a one-way system, through a tri-axial shaking table test. The attention of this study focused on evaluating the seismic qualification of the prototypes based on ICC-ES AC 156. In particular, the influence of the mounting position of prototypes at the ceiling, steel frames, walls, and beam or column on the seismic response of the building was also discussed in detail. The seismic performance in terms of acceleration and displacement response was also evaluated by power spectral density-based (PSD), and root mean square-based (RMS), which showed a better seismic response of H-beam frame type than other types of pulley-type wireway system. Finally, it was determined that the newly developed lighting support with the addition of a pulley is capable of dissipating seismic energy more effectively than the previous lighting equipment system.
