The analysis will automatically discount any reinforcement that is present at an opening. For mild reinforcement, it will cut it exactly at the block out and will not add in cover.
Strand
By selecting a row in the grid the user can edit the lateral position of the strand by either giving the offset from the previous strand or the strands location from the rail.
The add minimum button will automatically add the minimum amount of strand, assuming a 15% loss in prestress. The strand will also automatically be evenly spaced across the width of the panel.
The mirror strand button will copy the selected row and mirror it about the c.g. of the panel for insulated panels, and relative to the faces for other types of panels (using the cover).
Header | Description |
|---|---|
Size | Select from a predefined list of sizes, or assign a custom size. |
Area | Area of the strand (required for custom sizes). |
Diameter | Diameter of the strand (required for custom sizes). |
Quantity | Quantity of strands |
% Pull | Pull fraction that is multiplied times ultimate stress to obtain pull stress |
Depth to CG | Depth of the prestressed reinforcement. |
Top Debond Length | Length of any debonding starting at the top of the panel. |
Bottom Debond Length | Length of any debonding starting from the bottom of the panel. |
Save Pattern | Save the current strand pattern to disk. |
Open Pattern | Retrieve a previously saved strand pattern from disk. |
Rebar
The mirror rebar button will copy the selected row and mirror it about the c.g. of the panel for insulated panels, and relative to the faces for other types of panels (using the cover).
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 | Quantity of bars. |
Spacing | Spacings of the bars. |
Depth to CG | Depth of the mild reinforcement. |
Location from Left | Location from the left end of the panel where the reinforcement will begin. |
Start from Bottom | Start of bar as measured from the bottom of the panel. |
End from Top | End of bar as measured from the top of the panel |
Start / End Condition | 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 panel is assumed to be the bottom of the panel in the final condition. |
Mesh
Welded wire reinforcement (commonly referred to as ‘mesh’) is input as sheets instead of individual line and cross wires and their respective spacings.
Pressing the minimum reinforcement button will automatically add the a sheet of mesh in the panel (or in each wythe for insulated panels). This minimum amount is calculated from the required shrinkage and temperature reinforcement.
The mirror mesh button will copy the selected row and mirror it about the c.g. of the panel for insulated panels, and relative to the faces for other types of panels (using the cover).
Header | Description |
|---|---|
Line Wire Size | Size of the main line (vertical) wires. |
Line Wire Spacing | Spacing of the main line (vertical) wires. |
Cross Wire Size | Size of the cross (horizontal) wires. |
Cross Wire Spacing | Spacing of the cross (horizontal) wires. |
Type | Mesh reinforcement type. W is smooth wire and D is deformed wire. |
Depth | Depth of the WWR sheet. |
Loc from Left | Location from the left end of the panel where the WWR sheet will begin. |
Loc from Right | Location from the right end of the panel where the WWR sheet will end. |
Start from Bot | Start of the WWR sheet as measured from the bottom of the panel. |
End from Top | End of the WWR sheet as measured from the top of the panel. |
Reinforcement Interrupts
Reinforcement interrupts can be used to stop reinforcement at a given location. These are often used to cut reinforcement at joints between panels. The reinforcement will be removed over the entire length of the interrupt.
Header | Description |
|---|---|
Start | The location of the beginning of the interrupt measured from the bottom of that panel. |
Length | The length of the interrupt. |
Quantity | The total number of interrupts. |
Spacing | The spacing of the interrupts. This is the start to start spacing. |
Cut… | Options to cut strand, rebar, and / or mesh. |
