Illustration of how displacement random magnitude errors are generated. The spherical radius in (a) represents the maximum error magnitude ratio relative to the baseline measurement, which is capped at x%, with x ranging from 1 to 10 at a step size of 1. For illustration, the range of displacements from 100 random trials for the x-component time-history is shown for a selected case (b), where the maximum displacement random error is capped at 50% to improve visualization (note, a maximum value of 10% was used in analysis). The displacement time history curve for a typical trial is also presented.
