Node Joints

Node joints (also called node connections) define how beams are connected at a node. By default, all beams meeting at a node are rigidly connected.

Types of Connections

• Rigid - Full moment transfer between beams
• Hinged - No moment transfer (pinned connection)
• Semi-rigid - Partial moment transfer using a rotation spring

Defining Node Joints

When multiple beams meet at a node, you can specify the connection type for each beam end:

1. Select the node
2. Open the properties dialog
3. Set the connection type for each beam

Spring Connection

For semi-rigid connections, you can specify a rotation spring stiffness. This is useful for modeling:

• Flexible connections
• Partially restrained joints
• Specific joint behavior
