Vibration analysis of the structures with identical parts using Finite Element Method

In many engineering structures, and especially in the field of civil engineering, there are systems that have identical parts or that have certain symmetries. These structural properties give the possibility to ease the design and calculation in such circumstances. Thus, the analysis time can be reduced and the quick estimation of the response offered by the structure in different operating conditions can be reduced. As a result, the cost price for building the structure decreases accordingly. The symmetries of the structures and the existing identical parts also allow an easier analysis in the case of the study of vibrations. In the work, specific vibration properties of a structure containing identical parts are highlighted. An example for a real-life structure will argue the presented results.
