Dynamic analysis of steel mast under some environmental uncertainties
(Wydawnictwo Politechniki Łódzkiej, 2022) Bredow, R.; Kamiński, M.
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Random Response of Steel Hall Subjected to the Dynamic Excitation by the Generalized Iterative Stochastic Perturbation Technique
(Wydawnictwo Politechniki Łódzkiej, 2021) Bredow, R.; Kamiński, M.
This work aims to analyze the random response of steel halls subjected to dynamic wind excitation. The investigated object has recently been erected in central Poland and its mathematical model has been created in Abaqus 2017 software. The model includes the warp of beam elements involved in the structure which adds additional value to this work. Dynamic analysis has been performed with the Hilber- Hughes-Taylor algorithm and recovered responses undergo further approximation in polynomial form for probabilistic analysis. Several uncertainties of mechanical and environmental nature are investigated. Generalized Iterative Stochastic Perturbation Technique has been contrasted with Monte Carlo Simulations and Semi-Analytical Approach. Conclusions from this comparison are discussed in this paper.
