Temporary structures, such as grandstands, are commonly used during different types of mass events, especially sport and music concerts. In this paper, the results of the experimental study on temporary steel grandstand are presented. The aim of the investigation was to determine modal characteristics of such structures. Modes of free vibrations and corresponding natural frequencies have been obtained for empty and occupied grandstand. The results of the study confirm that crowd provides additional mass that has a significant influence on the structure and leads to a substantial reduction in values of natural frequencies.
