COMPARISON OF DYNAMIC COMPUTATIONAL MODELS IN DETERMINING FREQUENCIES AND FORMS OF NATURAL VIBRATION OF THE LARGE-SPAN STEEL TRUSS OF THE VELODROME BUILDING ROOFING
Frequencies and natural vibration forms are determined by means of dynamic computational models of various degrees of accuracy for the large-span steel truss of the velodrome roofing. A simplified engineering formula is proposed, that allows to determine the first natural frequency of the truss under research for any symmetric mass distribution.
