Nowadays, it provides a fast and economical technique for studying the dynamic behavior of real full-scale structures. In this paper, this approach has been utilized to evaluate the finite element (FE) results in order to achieve the modeling update that will lead to have a full-scale simulation between the mathematical model and the actual structure. Four studied cases of existing reinforced concrete buildings commonly used in Egypt have been chosen and examined by an accelerograph in order to extract the corresponding natural frequencies and mode shapes. In addition, a 3D FE model for each case was created and its results were compared with previous extracted data by taking into consideration two affecting factors of the materials used in these structures. These are the concrete strength and the brick Young's modulus. The process of modeling update was suggested for each case and a number of conclusions and recommendations are given.
