Experimental Modal Test of the Laboratory Model of Steel Truss Structure
By: Ján Kortiš, Ľuboš Daniel, Milan Škarupa and Maroš Ďuratný
Abstract
The experimental modal analysis is often used to validate the accuracy of dynamic numerical models. It is also a good tool to obtain valuable information about current condition of the structures that could help to determine residual lifetime. The quality of modal testing results is highly dependent on the proper estimation of the natural frequencies from the frequency response function. This article presents the experimental modal test of the laboratory steel structure in which the natural frequencies and mode shapes are determined.
