What features are used for pined connections in Abaqus?
Dear Dr. Yoosofpoor,
Thank you for your question. In Abaqus, pin connections between beam and column in steel structures can be modeled using the following approaches:
- Connector Elements (CONN3D2): Define connector elements with a hinge behavior, where rotational degrees of freedom are released around the desired axis while translational DOFs remain constrained.
- Connector Section: Use a Connector Section with appropriate mechanical behavior (e.g., hinge or cardan) to replicate the pin condition.
- Kinematic Coupling: Apply kinematic coupling with translational constraints only, leaving rotations free to simulate the pin connection.
- Surface-Based Interactions: If partial moment transfer is needed, define contact or interaction properties that limit moment capacity to simulate semi-rigid or flexible connections.
These methods enable flexible and accurate representation of pinned joints depending on the desired level of detail.
Kind regards,
