minimum spacing of ties in Columns and it's condition?

[Venkatshanthi]

Please any one explain minimum spacing of ties in Columns and it's condition...???

First divide the column length into three parts as
Let L be the total length of column
1)L/4 From the bottom
2)L/4 from the top
3) Remaining part(Central portion)
#Give the spacing of ties in bottom and top L/4 portion as minimum
& Reason :Stress on the column is maximum at this portion due to load transfer,in order to counter that ties are provided with minimal spacing.
#Give the spacing of ties in centre portion as maximum
& Reason:Stress is very less in centre portion and hence ties are provided with maximum spacing.
Example:
Suppose take a column of length 10m, stirrup (Ties)of Dia 8mm
#8mm @ 100mm c/c @ 2.5 m from both ends
#8mm @200mm c/c @ 5m in central part

Least lateral dimension
16d
300mm whichever is maximum

Any code book reference this answer..?

This is curtailment not spacing I think

There can be no GENERALISATION OF SPACING OF TIES in any structural member, it all depends on the STRUCTURAL DESIGNERS and hence can keep on changing based on the design parameters set out by the Structural Designer.

Almost it should be 75mm
