Abstract

Natural frequency of any natural or artificial material play a role in selection it for industrial and manufacturing applications. Natural frequency for material meaning its ability to absorb external vibration for avoiding resonance. In the presented paper wood and steel will used as a type of natural materials, concrete also will used but as an artificial material. Calculation of natural frequency for each material will done with same volume of structure. Natural properties of wood show superiority for many mechanical applications. The aim of this study is to investigate the effects of various factors including characteristics of wood, steel and concrete on their natural frequencies with the aim of producing recommendations to promote sustainability. Fuzzy logic control system also implemented for optimizing the impacts of these characteristics on the structure' vibration. In addition, the natural frequencies of structures have been assessed against the wind, earthquakes, and traffic vibrations. The results reveal that for the same dimensions of the structure, wood shows the highest natural frequency, steel followed by concrete. Results indicate that wood can complement natural properties of a range of industrial manufacturing materials to promote sustainability and improve performance. This can have implications for heavy machines laboratories (like foundation for that machines) and other engineering applications.
