Abstract

This paper presents a finite element model updating procedure of historical Santa Maria Church in Trabzon, Turkey. This process involves ambient vibration method, which is non-destructive experimental measurement, and numerical evaluation using finite element method. Scope of paper, the experimental dynamic characteristics were identified of the church building and the initial finite element model was developed. To minimize the differences between numerical and experimental dynamic characteristics, the manual FE model updating procedure was used. The maximum difference of 34.81% between the numerical and experimental frequencies was reduced to 2.22% with the FE model updating procedure and structural behavior was tried to be determined as close to actual as possible.
