Reduction methods for the dynamic analysis of substructure models of lighweight building structures

Flodén, Ola LU ; Persson, Kent LU and Sandberg, Göran LU (2014) In Computers & Structures 138. p.49-61
Abstract
In the present study, different model order reduction methods were compared in terms of their effects on the dynamic characteristics of individual building components. A wide variety of methods were employed in two numerical examples, both being models of wooden floor structures, in order to draw conclusions regarding their relative efficiency when applied to models of such structures. It was observed

that a comparison of the methods requires the reduced models to be exposed to realistic boundary conditions, free–free eigenvalue analyses being insufficient for evaluating the accuracy of the reduced models

when employed in an assembly of substructures.
