Assign Beam Line Numbers Automatic
Selecting the command causes the Assign Beam Lines dialog box to display. This dialog box allows the user to establish criteria by which the program will automatically assign beam lines to all concrete beams on all stories.

Beam lines and beam line numbering are a fundamental concept utilized throughout the program. Only concrete beams with assigned beam line numbers can be designed in RAM Concrete Beam.
Beam lines can also be assigned and modified manually using the command.
Note that the gravity beam fixities can be assigned to the gravity concrete beams at the same time the beam line numbers are assigned or manually at any later time. Select the appropriate assignment of fixity from the Assign Beam Line dialog.
| Setting | Description |
|---|---|
| Include Beams with Variance Angle Less Than | The angle specified in this edit box defines the maximum angle, between two contiguous beams, for them both to be assigned the same beam line number. Any angle larger than this and the beams will be assigned different beam line numbers. |
| Beam offset to accept as continuous | This distance defines the offset that can exist between two continuous beams for them to be assigned the same beam line number. The beams in this case need not be truly continuous as some offset exists between the ends of each, but they will be designed as one continuous beam. |
| Gravity Beam Fixity | When assigning or removing beams from a beam line the program can automatically assign end releases or fixity to the selected gravity, concrete beams. To have the program automatically assign beam fixities the Automatically Assign Beam Fixities checkbox must be selected. Select between Fix all beams and Release All Beams to have the program Fix or Release, respectively, the ends of the subsequently selected gravity, concrete beams. Fixed beams will be considered continuous in the analysis. Pinned beams will be considered released for bending at each end but will remain fixed for torsion. |
Example
The beam line numbers shown below will be generated for the indicated criteria.
- Include Beams with Variance Angle Less Than 40 Degrees
- Beam Offset to accept as continuous = 3 inches
Note that the beams offset 3 inches are assigned the same beam line number, but not those offset 6 inches. Also the beams that are within 40 degrees of each other are assigned the same beam line number.
