WebGiven a earthquake ground acceleration, there is no difficulty to compute response using Newmark’s method as the previous example. Therefore, we can generate a response spectrum for that earthquake. We are interested in the maximum relative displacement, velocity, and total accelerations. These quantities are generally referred to as WebVelocity in Agile is a simple calculation measuring units of work completed in a given timeframe. Units of work can be measured in several ways, including engineer hours, user stories, or story points. The same applies to timeframe; it’s typically measured in iterations, sprints, or weeks. WebWe estimated PSA slope from the slope of the least squares regression line fit to PSA versus time in years; PSA velocity was calculated as the running average of the rate of change during at least three consecutive assays. The acceleration of PSA (lnPSA slope) was calculated as the slope of lnPSA versus time, where ln is the natural logarithm. theory of a deadman no surprise
