Peak particle velocity earthquake

WebJun 1, 2016 · The parameters associated with the vibration are displacement, velocity and acceleration with their respective frequencies. It has been inferred from literature that peak particle velocity (PPV) is generally a good index of damage to structure (IS 6922, 1973, Monjezi et al., 2010, Kumar et al., 2012). WebThe one most accepted in the field as an indicator of damage potential is the peak particle velocity ( PPV). [12] As the name implies, PPV is a measurement of maximum ground particle movement speed. It is specified in the U.S. in inches per second (in/sec) and in most of the rest of the world in millimeters per second (mm/sec).
