Modal analysis of temporary steel grandstand equipped with different bracing systems
The aim of this paper is to present the results of numerical analysis focused on temporary steel scaffolding grandstand. The investigation has been devoted to modal analysis where modes of free vibrations and corresponding natural frequencies have been estimated and compared. The structure was equipped with different types of stiffener members. One on them is a typical tubular stiffener, while the second one is spe-cially designed polymer element. Two different types of bracing system have been considered. Shell as well as beam and solid elements have been used in the numerical model. The results of the study clearly show that the values of dynamic parameters for different types of bracing systems are substantially different.
