XBeam2D Supports

Standard supports can very easily be added in the graphical screen. In the menu bar you can choose for one of the following supports:

Remark

These are the supports that are the most common in practice, but you can also add an arbitrary (spring) support by making use of the 'A', 'P', 'N' or 'S'. See the table below.

Pinned support (Tz,Ty,Rz) ( 'A','A',' ')

cur_restrain_rollerX Roller support z-direction (Tx,Tz,Ry) ( ' ','A', ' ')

res_rol_z Roller support x-direction (Tx,Tz,Ry) ( 'A',' ', ' ')

res_vast Fixed support (Tx,Tz,Ry) ( 'A','A', 'A')

res_spring_x Springer support x-direction (Tx,Tz,Ry) ( 'S',' ', ' ')

res_spring_z Springer support z-direction (Tx,Tz,Ry) ( ' ','S', ' ')

res_spring_r Springer support y-direction (Tx,Tz,Ry) ( ' ',' ', 'S')

In this modus you can apply multiple supports by the use of the left mouse button. By placing the support, you will see the coordinates in the right bottom. As is shown in the image below.

Supports can be added arbitrary, in a fixed raster or on grid lines.

Supports are nodes that can't move in a certain direction.

Changing a support

Changing a support is possible by clicking on the node by use of the left mouse button, and subsequently choose for properties by clicking on the right mouse button. There also is a more easy way, namely by a double click on the node. Consequently the following dialog box will be opened.

Indication

Description

' '

free - no limitation 

'A'

Fully limited  (Absolute) 

'P'

Limited for a Positive reaction force; free for a negative reaction force

'N'

Limited for a Negative reaction force; free for a positive reaction force

'S'

Spring (Spring); spring value needs to be inserted

Table Nodes

Supports can also be added/changed in the table nodes in the left bottom. It does not matter. It is also possible to change in between graphical input and numerical input via tables.
