For other peak accelera- tions, this PSD requirement should be scaled by the square of the peak accelera- tion. The one-sided PSD is related to the Fourier amplitude IF M I of the time history by the equation 2 1F(W 12() S __()..................;..(1 0 (w) -2zn TD where T is the strong-motion duration over which F is evaluated. This duratioR T represents the duration of near maximum Aid nearly stationary power of aR acceleration time history record. Additional guidance on estimation of T for artificial time history or actual earthquake time history is provided in Rppendix B of
