velocity spectrum intensity
Posted: 27 Jul 2017, 07:44
Hi, how can calculate velocity (VS) spectrum intensity for a specific target acceleration response spectrum؟
Hi ghanbari. The equation is given in the SeismoSignal Help system as the area under the pseudo-spectral-velocity versus period curve between 2 particular periods (0.1 and 2.5 seconds in the Help system). Given only the acceleration spectrum, one could compute the PSV spectrum by substituting the following in the equation for VSI, and then performing the integration.
Sv=PSV=SA x g x T / (2 x pi)
