Özet

Toward the assistance on selection of ground motion prediction models for seismic assessment, this article presents a seismic hazard study (compared to the viewpoint of attenuation equations), using a recent tool based on engineering judgment, called weighting factor, through a procedure similar to logic tree. For this purpose, the weighting factors were incorporated with a Venn diagram of attenuation models regarding experimenter's concern and expert's knowledge. It is found that the attenuation equations of the newer and intersection ones could be considered to estimate plausible and reasonable accelerations. The results indicate that the weighting factors could beneficially assist for suitability of attenuation models. This work is a novel for the region (Gaziantep, Turkey), thus it could complement expert's knowledge about the attenuation models for future studies.
