Abstract—Today, civil engineering structures suffer from dynamic effects. Earth on structures have been severely damaged by the earthquake. Thus, there has been loss of life and property. This has particularly affected countries located on active fault lines. Pre- and post-earthquake measures have been developed in world. For these reasons, it is necessary to determine the dynamic performance of structures around the world. There are various methods for determine the dynamic performance. System identification is one of these methods. Mathematical model of the structural system is obtained by system identification method. Fuzzy Logic can be a system identification method. It is known as fuzzy logic, an algorithm for the mathematical projection of the natural, in other words, human intelligence. In this study, steel model bridge was used as test subject. MATLAB software is used. In this study, it is aimed to estimate the output of steel model bridge with fuzzy logic. The output data of the model steel bridge was first obtained on the experimental modal analysis and then the output data obtained with fuzzy logic were compared. As a result of the comparisons, it was observed that a nearly 99% compliance was achieved. In the light of all results, it is seen that fuzzy logic method will be useful in system identification method in civil engineering field.
