Abstract:

The earthquake of a region, local ground conditions and structural characteristics are important parameters used in determining the behavior and risks of structures under the earthquake impact. In structural analyses, the earthquake of that area can be expressed by spectrum curves. In 2019, the Turkey Building Earthquake Regulation has started to use specific spectrum curves to the point. In the framework of this study, one province from seven different geographical regions in Turkey has been selected and the geographical location has been determined to determine the level of impact on both earthquake parameters and construction performance calculations. For Ankara, Antalya, Diyarbakır, Erzurum Istanbul, İzmir and Samsun, the chance of vaccination in 50 years is 10% (475 years) and the place movement level indicated as DD-2 in the Turkish Building Earthquake Regulation has been considered as the local ground class ZE. Short-period map for each province is calculated for the spectral vibration rate, the greatest ground vibration, the greatest ground speed, the local ground impact ratio, the design spectral vibration ratio and the horizontal and low elastic spectral curve. The study has been studied in different geometric locations, but despite the same ground characteristics and ground movement, the change in earthquake parameters has been studied. In order to reveal the impact of the geographical position on the structure performance calculations, a seven-storey concrete structure with the same structural characteristics has been selected in all the provinces. Analysis has been carried out for each province for the selected sample concrete structure. Static adaptive push analysis is used in the structure analysis where the ground characteristics are taken into account. All the results are compared. The geographical location change directly affects both the earthquake parameters and the structural analysis results. The study revealed that the building earthquake regulations in Turkey are an achievement of special earthquake parameters in the field. Even if the local ground conditions and structural characteristics are the same at any point, the earthquake elements in the area should be taken into account.
