Structural Model Updating Using Experimental Static Measurements

Abstract

The results of experiments on a small scale steel frame model are presented to support the “displacement equation error function,”“displacement output error function,” and “strain output error function” methods of structural parameter estimation using static nondestructive test data. Both static displacement and static strain measurements are used to successfully evaluate the unknown stiffness parameters of the structural components. Weight factors calculated from the variance of the measured data are applied to reduce error in the parameter estimates.
