Finite element modelling of jointed structures

Abstract

Many engineering problems involve the modelling of discontinuities within continuous systems. As it is difficult and often impossible to obtain a closed form solution a numerical approach must be adopted (e.g., finite element method (FEM)). In studying the panelized problem several FEM models were found in the literature. The primary objective of this note is, therefore, to discuss and compare three FEM models for layered joint response. The specific example that is considered is the panelized concrete wall–floor joint. Joint response is compared using each FEM model at both service loads (for the essentially linear elastic situation) and overload.
