For periods less than smaller Tcorner, the design spectral response acceleration, S, shall be taken as as a linear function.
For periods greater than or equal to small Tcorner value and less than or equal to greater Tcorner value the design spectral response acceleration, S, shall be taken as equal to maximum spectral response acceleration.
For periods greater than or equal to graeter Tcorner value the design spectral response acceleration, S, shall be taken as a fuction of T and spectral response acceleration parameters.
