Search "Seismic" in Ansys Help. There are lot of examples in help to start with.
For example-
6.8.4. Example: Multi-Point Response Spectrum (MPRS) Analysis
13.15. Example: Spectrum Analysis of a Cylindrical Tank Filled with Water

Also you can check following Verification Manual problem.
VM69 - Seismic Response
VM70 - Seismic Response of a Beam Structure
