✦ Synopsis

Abstract

The usual linear shape function for approximating axial displacement in beam finite elements used as eccentric stiffeners leads to an inconsistency which can result in large errors in the deflection of plates or composite beams. The introduction of an additional degree‐of‐freedom for these elements circumvents this problem.

## Abstract The usual linear shape function for approximating axial displacements in beam finite elements used as eccentric stiffeners or as portions of composite cross‐sections, leads to an error in the static deflection. A modified element reduces this error. The behaviour of these two elements u

In this paper an extension of the antiresonance-based model updating method that}by estimating antiresonances of unmeasured point FRFs}allows the use of previously identified modal data, is applied to the finite element model updating of the GARTEUR benchmark. The various steps of the process (model
