The effects of different storey heights on structural behavior of RC buildings according to 1998 and 2018 Turkish earthquake codes: comparative study

Turkey is located on active fault zone. For this reason, earthquakes are an inevitable reality for Turkey. In our country, where major earthquakes occur frequently, there is a great loss of life and property. In order to prevent these losses, earthquake regulations are continuously updated. In this study, with the aim of comparing two different earthquake codes, numerical models of reinforced concrete structures with different storey heights were created and structural analysis were carried out according to the 1998 and 2018 earthquake codes. As a result of the analysis, the period, maximum displacements, relative interstory drifts, base shear forces and torsional irregularity coefficients were compared. As a result of the study, it was determined that the selection of a simple and symmetrical structural system could prevent irregularities, but the structural system was negatively affected when the storey height increased.
