Application of Perturbation Methods to Improve Analytical Model Correlation with Test Data

There are current and future requirements to develop a systematic method to update a mathematical model of a structure to more closely match the test data. The effort is cost effective since the number of reanalyses of a large structure will be reduced. Additionally, the mathematical model will more closely represent its test data.

This activity describes the positive and negative experiences in using a method published by C. W. White and an extension of the method. The results are based upon our understanding of the method as published.
