AND STRENGTH-BASED GROUND MOTION PARAMETERS

Probabilistic seismic hazard analysis (PSHA) studies for the K. Çekmece site in Turkey have been performed using two ground motion parameters – the conventional spectral acceleration, Sa and an energy-based parameter with units of acceleration, Ai, which is derived from input energy. This energy-related acceleration parameter is used since it is expected to provide more useful information regarding damage potential compared to conventional strength-related parameters (e.g., response spectral ordinates). Uniform hazard spectra for three different return periods are presented for the K. Çekmece site including site effects. Finally, the uniform hazard spectra based on the strength-based parameter are compared with design spectra based on the Turkish building code
