Experimental Modal Test of the Laboratory Model of Steel Truss Structure

Experimental Modal Test of the Laboratory Model of Steel Truss Structure

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...
