Line support on a slab

Parameters

Name

Specifies the name of the support.

Constraint conditions

See table below.

Constraint conditions

Free

The support is free in the specified direction. That is it imposes no constraint in the direction.

Rigid

The support in fully rigid in the specified direction.

Flexible

The support is flexible (elastic) in the specified direction. The user has to define the required stiffness of the support.

Rigid press only

Same as pure Rigid but the support acts ONLY under compression. If the support gets under tension it stops acting.

Flexible press only

Same as pure Flexible but the support acts ONLY under compression. If the support gets under tension it stops acting.

Nonlinear  Behavior defined by nonlinear function.

Geometry

System

The support may be defined in local or global coordinate system.

Edge

Specifies the edge where the support is located.

Position x1

Defines the starting point of the support.

Position x2

Defines the end point of the support.

Coordination definition

The position of starting and end point may be defined in absolute or relative coordinates.

Origin

Defines the origin for the coordinate system (above).

Note: A line support on the edge of a 2D member that was input as a shell member can only be defined in global coordinate system. If the user requires the definition of the constraint conditions in the local coordinate system of the slab, the 2D member must be input as a plane 2D member.
