A large number of accidents involving damage of temporary grandstands during different types of events were observed in the past. The aim of the paper is to analyse numerically the effectiveness of a polymer damper in damage reduction of a temporary steel scaffolding grandstand exposed to dynamic load due to jumping. The element has been installed as a diagonal one at the back part of the structure. The method has been compared with the typical solution of strengthening the grandstand with the diagonal stiffener of tubular cross section. The results of the study clearly show that the response of a temporary steel grandstand equipped with a diagonal damper as well as with the diagonal stiffener is substantially different. The application of the polymer damper leads to considerable reduction in the level of measured accelerations due to the increased structural damping preventing from damage.
