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

 

Then you create quadratic combination with the corresponding load factors for each of these spectral cases.

HOW DO IT?
