0011-4561 Static and dynamic analysis of the steel viewing platform Static and dynamic analysis of the steel viewing platform Górecka Anna author Bosak Grzegorz author Department of Structural Mechanics, Faculty of Civil Engineering, Cracow University of Technology, Cracow, Poland Correspondence to: Anna Górecka Correspondence to: Grzegorz Bosak gbosak@pk.edu.pl 09 12 2016 Budownictwo Zeszyt 1-B (6) 2016 2016 19 26 Copyright © 2016 2016 <p style="text-align: justify;"> This article outlines static and dynamic analyses of the viewing platform in Trzęsacz. The steel construction consists of two parallel lattice girders placed on concrete columns. The elements of the girders are made of tubular profiles. Ultimate limit state and serviceability limit state criteria were fulfilled in accordance with algorithms from Eurocodes. This paper also presents an analysis of the platform’s dynamic responses from rhythmical motion caused by human activity. The results of these calculations were checked with the comfort levels of people standing in the platform during the vibrations. Robot Structural Analysis Professional was used for the linear load case of static analysis and modal analysis.</p>
