The effect of different earthquake ground motion level on performance of reinforced-concrete structures

Site-specific design spectra are used within the framework of current earthquake resistant building design rules. Four different earthquake ground motion levels with different probabilities of exceedance were expressed with the current seismic design code. In this thesis, earthquake- structural parameters were obtained by taking into account four different ground motion levels for four different provinces with different earthquake hazards. Structural analyses were carried out using different earthquake ground motion levels obtained for each province. In the structural analysis, a sample reinforced-concrete structure with the same structural characteristics was selected. The results were obtained by using both ground motion levels and design spectra for four provinces. With this study, both the earthquake hazard and the ground motion level change were examined separately. It was determined that the two variables significantly changed the target displacement values expected from the structure.
