Different Modelling Approaches to Coupling Wall and Floor Panels within a Dynamic Finite Element Model of a Lightweight Building

This paper presents an investigation of a skeleton based coupling technique used for the assembly of different modules, i.e. walls and floors, in a modular finite element model. For simplicity the skeleton is introduced in the intersections of the panels. In this way all panels can be constrained to the global skeleton, leading to a removal of the constrained degrees of freedom (DOFs) in the individual panels. This artificial skeleton will inevitably influence the surrounding structure as the skeleton will be a physical part of the model. This issue is addressed. Furthermore, decoupled pseudomodes of the skeleton are discussed and analysed
