How to calculate cutting length of stirrups | formula for cutting length of stirrups 

1) shuttering area calculation for column Given column size = 0.3m×0.4m Height of column = 4m shuttering area calculated in square metre. Column need shuttering which cover 4 face only, bottom and Top face of column do not need shuttering. Area = perimeter×height of column Area = 2(0.3+0.4)×4 m2 Area = 1.4×4 m 2 Area = 5.6 m 2 Hence shuttering area of column is about 5.6 square metre 2) shuttering area for beam It is also measured in square metre, beam have also six face shuttering is calculated in only of five face ,top face is is not measured which is filled with concrete. Suppose beam size =0.225×300 m Width=0.225m, thickness=0.3m Length of beam is=4m Shuttering area of five face Face1= 0.225×0.3=0.675m2 Face 2=0.225×0.3=0.675m2 Face 3=0.225×4=0.9m2 Face 4= 0.3×4=1.2m2 Face5=0.3×4=1.2m2 Face 6= top face not measured Total area=4.650 sq m 3) for slab Its measures only in bottom of slab lenght ×width Top face not provided with shuttering Four side which is 5 or 4 inch thick slab side wall of slab supported by beam which is calculated in shuttering of beam Area of bottom face=4×5=20m2

Thanks Pravesh ji

Correct 40

40

Beam me 25mm lete hai, columns me 40mm (minimum )
