## Function

- Define types and magnitudes of Plane Loads. The Plane Loads defined by this feature are applied to the structure through the Assign Plane Loads feature. The Plane Loads can be applied to any specific locations on plate and solid elements, which constitute an analysis model. This capability alleviates the cumbersome tasks of locating nodes where loads are applied. The defined loads are converted into nodal loads based on the stiffness of the plate and solid elements and applied to the contiguous nodes.

## Call

From the main menu, select **[Load] tab > [Type : Static Loads] > [Pressure Load] group > [Assign Plane Loads] > [Define Plane Load Type]**

## Input

Plane Load Type dialog box

### Plane Load Type & Description

**Name** : Specify the name of Plane Load. The Assign Plane Loads feature refers to the Name when the defined plane loads are applied to the analysis model. Generally, true load types are specified, namely, Office, Equipment, etc.

**Description** : description of the name

### Plane Load

Define the load type, location, and magnitude, which will be loaded on the plane defined in the Loading Plane field of the Assign Plane Loads dialog box.

**Load Type**Specify the load type among Point, Line and Area loads.

**Point Load**

**x, y** : Coordinates of the point loads in the plane coordinate system, which is defined by the origin and x-y axes specified in the Loading Plane field of the Assign Plane Loads dialog box.

In the "Assign Plane Loads" dialog box, the plane load distribution is defined using three points.

**Force** : Magnitudes of concentrated loads

**Moment** : Magnitudes of concentrated moments

**Line Load**

**Uniform** : Check if the line load is uniformly distributed

**Type** : Specify the type of the line load

**x1, y1** : Starting coordinates of the line load on the plane coordinate system

**x2, y2** : Ending coordinates of the line load on the plane coordinate system

**Load** : Magnitude of force/moment at each location

In the "Assign Plane Loads" dialog box, the plane load distribution is defined using three points.

**Area Load**

**Uniform** : Check if the plane load is uniformly distributed

**Point** : Number of points defining the loaded plane

**x1, y1** : Coordinates of the first point defining the loaded area

**x2, y2** : Coordinates of the second point defining the loaded area

**x3, y3** : Coordinates of the third point defining the loaded area

**x4, y4** : Coordinates of the fourth point defining the loaded area

**Load** : Magnitudes of loads at each corner of the loaded area

The corners of a polygon defining the loaded area must be consistently specified either clockwise or counterclockwise.

We may find it more convenient to coincide the plane coordinate system with the global coordinate system or user coordinate system, which allows us to use the mouse editor and point grids to enter the last loaded location.

**Copy x-Direction**

Copy the defined plane load in the x-direction by specifying copy distances.

**Copy y-Direction**

Copy the defined plane load in the y-direction by specifying copy distances.

Click the Add button to include the defined plane load in the list. Click the Modify button to change the entered data and the Delete button to eliminate previously defined plane loads.
