For a particular spectral peak, the dichroic ratio R is defined by the relationshipR = A⊥/A∥where A⊥ and A∥ are the absorption of the LB films when the light is …
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… WebSep 3, 2024 · Spectral acceleration at roof. Peak ground acceleration (PGA) is defined as the maximum ground acceleration that occurred during ground motion at a site. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a location during a specific earthquake.
