FAQ, STATIK, Question 4

How do I define a specific response spectrum?

The microzonation of certain areas lead to special spectra, which can not be covered by the standard parameterized types.

Such non standard spectra are defined either by a set of curves or by a set of the parameters S, T_B, T_C, T_D used in the formula for the standard spectra. The program supports both types of input. They are described in chap. C 2.3 (generation 8) or chap. C 4.2 (generation 7) of the manual.
