Behaviour of the spectators in the grandstands during a sports match may generate excessive vibration that can cause problems with the serviceability limit state. Construction of modern stadium due to architectural design and improving the material properties of the elements are made more efficient. In this article we are dealing with modal analysis of structures Ondrej Nepela stadium in Bratislava and finding natural frequencies adjacent grandstands. The mods of natural vibration and natural frequencies were calculated by the computational model in computer program Scia Engineer with using the Lanczos mathematical method. The mods of natural vibration of construction is the motion of the construction in the direction of least energy expenditure, with which we can predict the behaviour of construction under dynamic loading.
