Strand
The analysis will automatically discount any strand that is present at an opening. You can change the location of individual strands by selecting a row, which opens up another grid row that lists the horizontal offsets of each strand from the previous (the first entry in this row is the distance to the left edge of the column).

Rebar Table
Header | Description |
|---|---|
Size | ASTM bar size of reinforcement. If custom is selected, custom bar area and diameter must be entered. |
Area |
...
Bar area for the selected bar, and is not editable when an ASTM bar size is specified. When a ‘Custom’ type is specified, the user must input this value. | |
Diameter |
...
Bar diameter for the selected bar, and is not editable when an ASTM bar size is specified. When a ‘Custom’ type is specified, the user must input this value. |
...
Quantity |
...
Input the # of rows and columns of strands. | |
Edge Distances |
...
Distance from the corresponding edge (Left, Right, Back, or Front) and the c.g. of the closest strand row or column. | |
Position Down Length |
...
Position along the length of the member input as the start of bar as measured from the bottom of the column, and the end of bar as measured from the top of the column. | |
End Conditions |
...
Here you can select between five different end conditions: straight, 90 degree hook, 180 degree hook, headed, headed, and anchored (always assumed to be 100% developed). These end conditions are used in calculating the development length. The start of the column is assumed to be the bottom of the column in the final condition. |
Transverse
Transverse reinforcement (ties) may be added in this section. Typically these consist of individual rectangular ties spaced evenly along the length of the member (sometimes with multiple ties spaced closer together at the ends of the member or below corbels). Continuous spirals are also supported.

For spirals, this is the start and end of the spiral. | |
Required Covers |
