Abstract—Today, civil engineering structures have dynamic effects. The land in the buildings has been severely damaged by the earthquake. Thus, loss of life and property was experienced. These countries are particularly affected in active fault lines. The pre- and post-earthquake measures were developed in the world. For these reasons, it is necessary to determine the dynamic performance of structures in the world. There are several ways to determine dynamic performance. System definition is one of these methods. The mathematical model of the structural system was obtained by the system identification method. Artificial neural networks (ANN) are a method of identifying the system. Artificial neural networks (ANN) can adapt to their environment, adapt and work with incomplete information and make decisions under uncertainty and tolerate errors. In this study, a steel model lighting pole was used. The system identification of the model lighting pole using the 0.999 ANN method was successfully performed. As a result of this study, the ANN approach can provide a very useful and accurate tool for problem solving in media identification studies.

I. INTRODUCTION

Most buildings located in earthquake-prone areas suffer various damage caused by seismic loads. [5] There are many studies that take this into consideration. In seismic danger zones, structures are expected to vibrate due to seismic loads [15]. In the field of civil engineering, there are currently many types of structural and architectural structures. These structures can be managed by effective resistance to static and dynamic loads [16], and further studies are needed to clarify the performance of structures under seismic loads [13]. Further research is conducted to obtain the necessary performance for seismic loading structures by considering different perspectives and trends [14]. In recent years, determining the impact of vibrations on structures and structural behavior has become very important in the world and in our country [17]. Buildings located in seismically active areas are at risk of severe damage from harmful seismic loads.
