accepted on a case- by-case basis. 6. Three Components of Earthquake Motion. RG 1.92 describes acceptable methods for combining the responses due to three components of earthquake motion, for both the response spectrum method and the time history method. Use of alternate methods is evaluated on a case-by-case basis for acceptability. When the three components of earthquake motion are applied simultaneously, using a set of three artificial time histories, the statistical independence of the time histories should be demonstrated. See subsection II.1.B of SRP 3.7.1 for the acceptance criteria to demonstrate statistical independence.
