Answer Posted / shashank
IN CASE OF COLUMN-
DIM.-200X400mm
CONCRETE COVER-
FOR COLUMN THICKNESS <250mm=25mm
FOR COLUMN THICKNESS >250mm=40mm
LENGHT OF TIE- 2A+2B=2X200+2X400=1200mm
NOW DEDUCT CONCRETE COVER-LENGTH OF TIE-COCNRETE COVER=1200-
2X40=1120MM
ALSO, DEDCUT BENDS- 2D FOR 45degrees
D FOR 90degrees
THEREFORE- CUT LENGTH OF TIE-1120-DX5=1120-2X8=1104mm(NO.
OF BENDS -5 )
Length of Hooks=10d=10x8=80MM
NO. OF hooks=2
Therefore-Length of Hook=2x20=160MM
CUTTING LENGHT OF BAR=1104+160=1264MM=1.264m
