Defining Nodal Supports

This section shows you how to create nodal supports for four corner nodes of the bridge. Click the button to assign a support to a node. This is created using .

Assigning Nodal Supports

For Node 1, select a fixed support for all translational displacement options.

Node 2 is supported in the X and Z directions.

Support on Node 1 and Node 2

The nodal supports for Node 3 and Node 4 can be generated in the same way. Node 3 is supported in the Y and Z directions; Node 4 in the Z direction only.

The modeling of the truss bridge in RSTAB 9 is complete now.
