Abstract :Earthquake input motions perform critical role in the design of new or retrofitting of existing buildings. Therefore, modern seismic design codes guide engineering practitioners in delivering standard design response spectra for different soil classes. In this study, the applications of EC8 and TBEC design response spectra in the high-seismicity region of Kocaeli are evaluated. For that purpose, firstly, the seismicity of Kocaeli region involving the 17 August 1999 (Kocaeli) earthquake event is presented. Secondly, design response spectra of these two codes are compared with each other and with the spectral response curves of the actual input motions recorded at four different soil classes. Later, two reinforced concrete building models are analyzed by means of response spectrum analyses. Based on past seismic activities, the area is always prone to earthquake events, possibly occurring with magnitudes greater than 5.0. Also, the characteristics of the Kocaeli earthquake input motions were shown to be altered by the changes in the soil deposits. Besides, both seismic design codes are able to provide design response spectra covering the actual spectral values well at each soil class in the Kocaeli region. The results of building analyses suggest that the EC8 design response spectra offer more conservative building shear forces, followed by the TBEC and the actual ones.Keywords : Saha etkisi, Sismik tasarım kodları, Tasarım davranış spektrumu, Tasarım spektrum analizi, Zemin sınıfları
