  There are different kinds of intensity measures to characterize the main
properties of the earthquake records. This paper proposes a simulation-based
approach to compute correlation coefficients of motion duration and intensity
measures of the earthquake ground motions. This method is used to investigate
the influence of the ground motion data set selection in resulting
duration-intensity correlation coefficients. The simulation procedure is used
to tackle the problem of inadequate available ground motions with specific
parameters. Correlation coefficients are investigated in three different cases.
In case one, simulated ground motions differ in terms of earthquake source
parameters, site characteristics, and site-to-source distances. In case two,
ground motions are simulated in a specific site from probable earthquake
events. In case 3, ground motions are simulated from a specific event in
different sites. The first case doesnt show a significant correlation, while
the second and the third case demonstrate significant positive and negative
correlations, respectively.
