how we can calaculate cutting lengh for stiruups 6mm dia .
column size 20 cm x 30 cm, cover 20mm
Answer Posted / naresh
if columns is 20x30cm
convert 1 cm=10mm
so 20cmx10=200mm
same 30x10=300mm
than
200-40=160 cover block
300-40=260 cover block
=(160+260+10d)*-2d
=(160+260+60)*-60
=900mm
i.e. 90cm (if cover block use in face of stiruups)
or if cover block are using with face of vertical bar of columns stiruups cutting length should be
(160+260+60+10)*2-60=920MM ie 92cm
