Span length, web properties (depth, width, spacing and number), slab thickness and tributary width define these systems. They can vary span by span. This system does not allow asymmetry.
| Setting | Description |
|---|
| Length |
The span length from center to center of supports. |
| Setting | Description |
|---|
| W Depth |
The joist web structural depth (including the flange depth). |
| W Width |
The joist web width. |
| F Depth |
The flange (slab) depth (thickness). |
| Pan Start Offset |
The distance from the beginning (or left hand end) of the span to the pan (or void former). |
| Pan End Offset |
The distance from the end of the pan (or void former) to the end of the span. |
| Additional Web Properties |
The following properties determine the tributary width for the whole model. The width cannot vary span by span. |
| Spacing |
The center-to-center spacing of the webs. |
| Number |
The total number of webs |
