Peak spectral acceleration
Spectral acceleration (SA) is a unit measured in g (the acceleration due to Earth's gravity, equivalent to g-force) that describes the maximum acceleration in an earthquake on an object – specifically a damped, harmonic oscillator moving in one physical dimension. This can be measured at (or specified for) different oscillation frequencies and with different degrees of damping, although 5% dam… WebResponse Spectrum Comparison Before and After Reducing PGA. (a) Peak ground acceleration is 0.42 g of original time process; Maximum value = 1468.30 m/g 2 (time: 7 s). Sampling frequency = 50.00 Hz, (b) Peak ground acceleration reduced to 0.260 g of time process. Maximum value = 484.75 m/g 2 (time: 6.64 s).
