Rigid Member

Glossary Term

A rigid member is a member element with a very high stiffness, which is used for the determination of rigid boundary conditions.

In order to avoid numerical problems, the stiffness of a rigid member is adapted to the rest of the structure. This member type is used for a rigid nodal constraints, which also allow for nonlinear restraints, eccentricities, member elastic foundations and member nonlinearities in contrast to the 'Coupling' member type. Furthermore, it is also possible to apply a load on rigid member.

Rigid members are ofter used to replace an eccentricity, to connect member elements with surfaces, and as 'spoke wheels' of a FEA connection.
