Beam systems
Span length, beam depth, beam width, slab thickness and tributary width define these systems. They can vary span by span.
| Setting | Description |
|---|---|
| Length | The span length from center to center of supports. |
| W Depth | The beam web structural depth (including the flange depth). |
| W Width | The beam web width. |
| F Depth | The flange (slab) depth (thickness). |
| Start Trib Width | The tributary (and hence slab) width at the beginning (or left hand end) of the span. For asymmetric strips, L Trib Start Width is the left tributary start width, and R Trib Start Width is the right tributary start width. |
| End Trib Width | The tributary (and hence slab) width at the end of the span. For asymmetric strips, L Trib End Width is the left tributary end width, and R End Width is the right tributary end width. |
