Abstract
Cevizlibağ Metrobus Overpass has a very important place in Istanbul transportation due to its high pedestrian density and its location on the main road with heavy vehicle traffic. Damage to the Cevizlibağ overpass in a possible earthquake may block the traffic of Istanbul and prevent the aid teams from reaching the earthquake victims. If it collapses in an earthquake while the density of people is high on it, it may cause many casualties. For this reason, this overpass should be designed in such a way that it will not be damaged even in the biggest possible earthquake. Also, there are 4 stairs on the overpass and a platform with turnstiles for Metrobus passes (Figure 2). This study aims to determine the dynamic (Modal parameters such as modal frequencies and mode shapes) and static properties (Geometry and material properties) of the Cevizlibağ Overpass and to examine the earthquake performance. In this context, the building was analyzed under the earthquake levels defined in the 2018 Turkish Earthquake Code. As a result of these analyzes, the total shear force capacity of the structure and the amount of shear force demanded from the structure were calculated using different earthquake levels.
