Download or read book Using Multiple Non-destructive Test Data Types and Data Sets for Condition Assessment of Bridge Decks written by Erin M. Santini and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several parameter estimation scenarios using a finite element model of the UCII-Grid were successfully completed using error function normalization, stacking and/or combing. The UCII-Grid stiffness parameters were updated to reflect the non-destructive test data. Only scenarios that used error function normalization and stacking were successful, in terms of physical meaning for the parameter estimates. The unsuccessful cases showed that no amount of numerical manipulation can make an ill-conditioned scenario produced meaningful results.
