Question { ERA, 4738 }

how to calculate triangular ring cutting length

Answer

For column cover is 40 mm both sides
here
300-40-40=220
600-40-40=520
For hook (10 times the dia meter of the bar)
so for 8mm = (80mm)
For bending (minus) 5X2d=5x2x8=80mm
Now the cutting length of the bar will be =
520+520+220+220+80+80-80
= 1560mm

ring size =220x520mm

What is difference between FSI & FAR,

Answer

FSI stands for Floor Space Index, whereas FAR stands for Floor Area Ratio. FSI and FAR are both related to the field of real estate. FSI and FAR both represent the calculation based on the ratio derived by dividing the Gross floor area with the total size of land on which the building is made. The terms may also be used in context to certain limitation attached with these terms.

Thus, simplly FAT or FSI = Gross floor area/ Area of the plot
