To add a static seismic load definition
To add a static seismic load definition containing code-specific loading parameters (i.e., an equivalent lateral force seismic load), use the following procedure.
Note: In addition to defining parameters for a seismic load case, you must also create one or more mass load groups to define the mass model for the structure. See To add a mass model load group for details.
-
On the
Catalog ribbon tab, select the
Add Seismic tool in the
Load Definitions group.
The Seismic Load Definition dialog opens. - Type a unique Name for the new seismic load definition.
- Select the options for the static seismic definition:
- Select the Code and Version from the respective drop-down lists to use for this definition. The list of Properties updates to reflect the parameters for the selected code.
- If the accidental load is to be considered, check the Include Accidental Load option.
- (Optional) For IS 1893 codes only, click the Generate button to open a dialog which is used to enter a simplified set of parameters per the IS 1893 code.
- Specify the code-specific static seismic Parameters.
- Click OK.
You can now use this definition for multiple static seismic load cases.
Selecting a seismic definition in the catalog will display its parameters in the Properties panel.
You can edit a seismic load definition by selecting it from the structure catalog and then clicking the Edit tool in the Edit group on the Catalog ribbon tab.
