Abstract

Jumping and hopping are considered the most severe human loading scenario for stadiums and gymnasiums. Recent design methods examine floor vibration by requiring knowledge of the dynamic characteristics of the floor structure (i.e., peak acceleration and fundamental frequency). However, these standards do not include a long and light structure such as the prestressed cable reinforced concrete truss (PCT) system considered in this study. Therefore, accurate assessment of the vibration behavior of such structures subjected to jumping and hopping is warranted. An experimental study (lab and in situ) aiming to investigate the vibrational properties and dynamic response of PCT floor systems was conducted. This study involves both jumping and hopping tests for verifying whether the characteristics are vibration acceptable. The measured responses of the floor systems were evaluated against the ISO 2631-2 limit for maximum acceleration. Lastly, a more rational method for determining fundamental frequency and peak acceleration is proposed.
