Study and Application on Structural Floor’s Comfort of Stadium with Long-Span Floor

Abstract

The structural comfort of long-span floor structure which setup stadium is studied in this paper. The measured spectrum is used to simulate human movement loads. All possible loads are considered and key parameters about structural comfort of the long-span floor structure are analyzed, and then, the comfort of athletes in match and audiences on the stadium stand are analyzed. The results show the vertical acceleration and natural frequency of structure are decreased approximate linearly with increasing of the slab thickness; take one engineering project for example, according to the method proposed in this paper, the different structural comfort control index should be adopted in sports field and audience stand, respectively. Comprehensive and system design references of load simulation, pre-stressed structure dynamic analysis, comfort performance index and control standards are offered in this paper for long-span pre-stressed steel floor structure project that used for stadium.
