Define Plane Load Type

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.

From the Main Menu select Load >Static Load >  Assign Plane Loads > Define Plane Load Type.

Click to initially define or add plane loads after providing the data below. Click or to change or eliminate the previously defined plane loads respectively.

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.

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
 

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

Note 1
The corners of a polygon defining the loaded area must be consistently specified either clockwise or counterclockwise.

Note 2
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 to include the defined plane load in the list. Click to change the entered data and to eliminate previously defined plane loads.
