M. To manually define and assign hinges
Use the following optional procedure to define parameters and assign hinges manually.
Note: If the pushover analysis will make use of the built-in FEMA hinge properties for all members,

On the
Loading ribbon tab, select the
Pushover tool in the
Define Loading Systems group.
The Create New Definitions / Load Cases / Load Items dialog opens with only the Pushover tab displayed.
- Select the Define Hinge Property tab.

Select the Hinge Type.
Types FEMA or Ignore do not require any additional parameters.

For user-defined hinge types only:
- Select an existing Type ID or select New Type to define a new hinge type.
- Specify a unique integer for the Type Identifier.

These values are calculated per Section 5.5.2.2.2 of FEMA 365 (Refer to G.17.4.1.6 Frame element hinge properties).

Once any other parameters have been added, click Close.
Entries for the hinge types are added in the Loads & Definitions dialog in the Definitions > Pushover Definitions section.
