3.2.11 Strong-motion parameters
Clicking on the ‘Strong-motion parameters’ button opens
windows displaying a selection of strong-motion parameters for
the selected time-histories. The parameters that are displayed
are (divided into the characteristic of the motion that the
parameter seeks to measure):
1. peak ground acceleration (PGA) in selected
acceleration units and the time at which this occurs;
2. peak ground velocity (PGV) in selected velocity units
and the time at which this occurs;
3. peak ground displacement (PGD) in selected
displacement units and the time at which this occurs;
4. RMS acceleration in selected acceleration units
calculated from
where T is length of record and a(t) is ground
acceleration;
5. RMS velocity in selected velocity units calculated from
where T is length of record and v(t) is ground velocity;
6. RMS displacement in selected displacement units
calculated from
where T is length of record and d(t) is ground
displacement;
7. A95 parameter in selected acceleration units, which is
defined by Sarma & Yang (1987) as the level of
acceleration that contains up to 95% of the total Arias
intensity;
