Error Indicator to Assess Quality of Finite-Element Frame Analyses
Publication: Journal of Structural Engineering
Volume 128, Issue 1
Abstract
The purpose of this article is to describe a tool developed in order to equip a finite-element software based on nonlinear beam analysis with an error indicator aimed at measuring discretization errors. The technique is an extension of the error estimate devised by Ladevèze et al. in 1991 in which the finite-element solution is compared to a statically admissible distribution of the generalized stresses. This last distribution is built element by element which is fast and easy to implement. A nonlinear analysis of a single bay frame in static’s is presented as an example.
