Selection of \ Ground \ Motion \ Prediction \ Equation (GMPE) is one of the key elements within a seismic hazard analysis. The variety of available GMPE models makes this selection a scientific challenge. Therefore, the stability assessment of a set of GMPE models is investigated in this paper by employing the new emerged Re-Sampling Analysis (RSA) methodology (Azarbakht et al., 2014). Four GMPE \ categories are examined in this paper which are: (1) The local GMPE models which are developed based on Iranian events; (2) Regional GMPE models which are for Europe and Asia; (3) The NGA-WEST1 GMPE models (Power et al., 2008); (4) The NGA-WEST2 GMPE models (Bozorgnia et al. 2014). The ground motion database, in this study, consists of 691 acceleration time series resulted from 85 seismic events. The magnitude range is between 5 to 7.4 and all the records have the distance less than 200 km (BHRC, 2013). The analysis is performed for spectral accelerations corresponding to the eight periods (T = 0.0, 0.1, 0.2, 0.5, 0.75, 1.0, 1.5, and 2.0 sec).The conventional statistical tools show good performance for nearly all the considered GMPEs, and they are not sensitive to the given database. However, the RSA results illustrate the bias versus magnitude, distance (
