Piping Input menu: Model > Seismic Wizard 
Wizards toolbar: Static Seismic Wizard
Selects a seismic code and its associated data.
The wizard computes the applicable g factor and fills in the appropriate data cells. X-component is set into Vector 1, Y-component is set into Vector 2, and Z-component is set into Vector 3; all other load components are set to zero.
A warning displays if the current element has uniform loads defined.
Because the wizard sets data in gravitational loading, you must verify other uniform load definitions for correctness.
