Spectral analysis

In Eurocode 8 I need to combine the earthquake horizontal with the vertical (For example Y +0.30X +0.30Z). The spectrum used in x and y is different from what is used in z.

In a spectral analysis can tell you how to combine the two earthquakes spectral different?

Thanks

In the exactly the same way. You define the X and Y cases with one spectrum and the Z with another. Then you create quadratic combination with the corresponding load factors for each of these spectral cases.

OK

HOW DO IT?
