Start and End Releases

Keywords

SRELEASE ERELEASE

Description

The two Release attributes, the Section Start Release (SREL) and the Section End Release (EREL), may be used to define how the Section behaves under the effect of applied forces and moments. They are relevant only for stress analysis of the structure.

The attribute settings allow for two types of movement of the Section ends when external forces are applied, namely:

• Linear movement along a specific axis (DX, DY, DZ)

• Rotation about a specific axis (RX, RY, RZ)

  Example
  SREL DX RX RY	The Start of the Section is constrained such that it can move only in the X direction and can rotate only about the X and Y axes.
