How can I import accelerograms?

[Anonymous]

Hallo,

how it is possible to import accelerograms in Time History Analysis? Of course, I have done a modal analysis first but it can't read the accelerograms. Is there any step-by-step?

I have attached 2 accelerograms.

Thanks in advance.

Hi @Anonymous

You need to correct thf file first

- delete  duplicated entries for 0 point

- correct number of lines

- replace commas by dots

Thank you so much for your help... Now the problem is that I have 3 pairs of accelerograms (directions X1,Y1,X2,Y2,X3,Y3) that i must import in THA and i must use combinations of them: G+0.3Q+X1+Y1, G+0.3Q+X2+Y2, G+0.3Q+X3+Y3. So what is the right way to do it?

Thanks in advance.
