Use the options on the Details tab to define parameters of connections in a cage.
For Vertical bars, define the position of bars with respect to the cage hoop, either Outside or Inside. You can also define the weld thickness for the hoop-vertical bar connection.
For Fixing, select either Welded or Bolted, and then specify parameters of the cage fixing to the ladder bars. For Radius of bending, define the radius of hoop bending at places where the hoop circular shape transforms into straight segments.
Under Hoop/ladder contact, specify the position of the hoop with respect to the ladder bar:
- External
- the hoop is aligned (facing operation) to the external edge of the ladder bar. - Internal
- the hoop is aligned (facing operation) to the internal edge of the ladder bar. - Axis
- the axis of the hoop cross-section and the axis of cross-section of the ladder bar are colinear (this type of fixing is available to a welded connection; it is not available when a bolted connection is selected).
Hoop-ladder bar connections are generated for every hoop. If a welded connection is selected, the software generates site fillet welds with user-defined thicknesses. If a bolted connection is chosen, the following 2 situations may take place:
- Bolts are put in round holes.
- Bolts are put in slotted holes - this is possible after you select Slotted holes; slotted holes are generated in hoops and their size equals the value of the hole diameter increased by 0.32 in.
Under Bolts, specify the bolt diameter and grade. Click Settings to display the Bolt settings dialog.
Under Enter widening, you can define parameters of the cage widening in its lower part. In the current version of the software, the widening is available only to the second type of cage.
The widening may start from the hoop you specify (1 denotes the lowest hoop). You can define the lower hoop radius; dimensions of the intermediate hoops are linearly interpolated.
After you define details of the cage geometry, click the Exit tab to display the Cages - Exit dialog.
