Closure to 'Vibration Studies of a Cantilevered Structure Subjected to Human Activities Using a Remote Monitoring System' by Mehdi Setareh

摘要

The author appreciates the interest of the discusser in the paper.As requested by the discussers, the author makes comments on the issues raised: 1. The discussers should note that the main objective of this paper has been to study the effects of human-structure inter actions in a high-occupancy floor structure. The modal testing was conducted as a reference to compare with the results of the analysis of the recorded measurements during events with high occupancies. It was possible to excite the structure with a shaker. The measured frequency response functions were of high quality, which was evident from the high coherences. The studies presented used an output-only method to study the variations of the dynamic properties of the system because of the presence of the audience and excitation of the structure during various musical performances.
