There are 2 parts to it.
First, you need to specify the seismic parameters. In the STAAD input file, it is a block of data that begins with
DEFINE 1893 LOAD
You can find examples here.

Secondly, you need to specify at least 2 load cases that contain the seismic loading. The commands in the STAAD input file will look like this
LOAD 1
1893 LOAD X 1.0
LOAD 2
1893 LOAD Z 1.0
If you are looking to specify a response spectrum loading per the 1893 code, there is another set of data for that. You can find an example here

Though all the above discussions deal with the commands in the input file, the GUI is easiest mode for creating this data. We will post a document sometime this week that shows the process for assigning these.
