Vibration Problems of an Example of Temporary Steel Grandstand under Human-Induced Excitation / Problemy Drgań Przykładowej Tymczasowej Trybuny Stalowej Poddanej Oddziaływaniom Dynamicznym Wywołanym Przez Ludzi

Lighter and slender structural members of a typical grandstand leads to significant reduction in the frequencies, that is why such structures are more easily induced vibrations. The aim present paper show results experimental tests numerical analyses focused on behaviour part temporary steel under dynamic loads. peak values accelerations scaffolding human-induced excitation have been determined compared with limit concerning perception vibrations by people. study indicate may induce which substantially exceed allowable limits.
