An equality constrained least squares approach to the structural reanalysis

Ho-Jong Jang

Hanyang University

Abstract

An efficient method for reanalysis of a damaged structures is presented. Perturbation analysis for the equality constra-ined least squares problem is adapted to handle structural reanalysis, and related theoretical and numerical results are presented.

Keywords: structural reanalysis, least squares problem, GQR factorization, perturbation analysis
