| Abstract: | CATAS ( Computer Aided Test and Analysis System ) is used for combining large scale static structural test and analysis. One of its aims is ensuring the consistency and reliability between structural analysis results ( FEM or engineering method ) and test measuring data. How to modify test based FEM models from the one used for designing is demonstrated. |
