## Function

Check the reactions at a particular support in numerical values.

## Call

From the main menu, select **[Results] tab > [Type : Anslysis results] > [Result Display] group > [Reactions] > ****[Search Reaction Forces/Moments]**

## Input

Search Reaction Forces/Moments dialog box

**Load Cases/Combinations**

Select a desired load case or load combination.

Click to the right to enter new or modify existing load combinations. (Refer to "Load Cases / Combinations")

**Step**

Specify the step for which the analysis results are to be produced. The Step is defined in geometric nonlinear analysis as Load Step, and additional steps are defined in the construction stages of bridges or heat of hydration analyses.

**Node Picking**

Assign a node for which reactions are to be checked.

**Node Number** : Enter the node number of a support, or click the entry field then click a support in the working window.

When the node number is assigned, the following items are displayed in the Message Window:

**Node Number** : Support node number

**FX** : Reaction component in GCS X-direction

**FY** : Reaction component in GCS Y-direction

**FZ** : Reaction component in GCS Z-direction

**FXYZ** :

**MX** : Moment reaction component about GCS X-axis

**MY** : Moment reaction component about GCS Y-axis

**MZ** : Moment reaction component about GCS Z-axis

**Fx** : Reaction component in the Node's local x-direction (when the node's local coordinate system is defined)

**Fy** : Reaction component in the Node's local y-direction (when the node's local coordinate system is defined)

**Fz** : Reaction component in the Node's local z-direction (when the node's local coordinate system is defined)

**Fxyz** : (when the node's local coordinate system is defined)

**Mx** : Moment reaction component about the Node's local x-axis (when the node's local coordinate system is defined)

**My** : Moment reaction component about the Node's local y-axis (when the node's local coordinate system is defined)

**Mz** : Moment reaction component about the Node's local z-axis (when the node's local coordinate system is defined)
