EFFECT OF HUMAN STRUCTURE INTERACTION ON BEHAVIOUR OF STADIUM STRUCTURE

Abstract

As more modern stadia structures built by making use of new high strength materials, makes the structure
lighter than the before. The result is that structures become more flexible, and thus they become susceptible to undergone
vibration problems due to the action of dynamic loading that can cause problems with the serviceability limit state. In the
stadium structure, the significant dynamic responses such as resonance or similar behavior can be occurred by spectator
rhythmical activities. Thus, accurate analysis and precise investigation of stadium structure that is subjected to dynamic
loads are required for practical design and serviceability check of stadium structures. Moreover, it is desirable to measure
and analyze the dynamic loads of spectator activities because these dynamic loads cannot be easily expressed in a numerical
formula. In this study, various dynamic loads induced by spectator activities like seating, walking, jumping etc. are
considered. These dynamic loads induced by spectators’ movement at stadium structure can be classified into the impact load
and the periodic load. These dynamic loads can be expressed as a harmonic load. And, these dynamic loads could be applied
for the accurate vibration analysis of a stadium structure considering human structure interaction.
In this study, floor vibration made by spectators’ movement at stadium structure will be considered by jumping of a single
person at each particular point and time history was made. This time history data were applied to the particular point of
jumping for vibration analysis and analysis of stadium structure part was carried out using SAP2000 software.
