(c) Ghaen (1976): The ground motion was recorded during Ms6.4, at a soil type I site, according to Iranian seismic building code, located at 10 km from the surface projection of the fault. PGA, PGV and PGD are .17 g, 24 cm/s and 6.5 cm respectively. The bracketed duration is 5.27 s.
WebFeb 28, 2024 · Bracketed duration ( D b ) is defined as the time elapsed between first and last exceedance of a specified level of acceleration. The change of threshold acceleration can significantly increase or decrease D b . In this study, the threshold acceleration values of 0.05 g (Bommer et al. 2009) and 0.03 g (Ambraseys and Sarma 1967) are considered. http://webshaker.ucsd.edu/homework/Ground_motion_parameters__Course_notes.pdf
