How do you calculate stirrup cutting length?
Cutting Length of rectangular stirrup = Perimeter + Hook Length – Bend length.
What is the formula for finding the length of steel in stirrups?
Length of X = Width – 2(Half the diameter of the bar) – 2(Clear cover). = 450 – 2(5) – 2(35). Length of Y = Height – 2(Half the diameter of the bar) – 2(Clear cover).
How do you calculate bar cutting length?
KNOW HOW TO CALCULATE THE CUTTING LENGTH OF BENT UP BARS
- Inclined Length = D/(sin 45°) – dD/ (tan 45°)
- = (D/0.7071) – (D/1)
- = (1D – 0.7071D)/0.7071.
- = 0.42 D.
What is the cutting length of stirrups?
A whose internal dimensions are “A” and “E”, let the corresponding external dimensions be “X” and “Y”. Thus, A=X-2d, E=Y-2d. Therefore, cutting length = 2 (A+E) + 24d = 2 (X-2d+Y-2d) + 24d = 2 (X+Y) + 16d.
What is cutting length of steel?
1) Cutting length of the main bar with hook Circled part is known as Hook whose length is 9d. 2d is subtracted to for bending of a steel rod at 90°. There are two bends in one hook length so, multiply it by two.
What is cutting length in BBS?
How to Prepare Bar Bending Schedule:
BBS of Column | |
---|---|
Dia of Bar | 1. Main Bars = 16mm ; 2. Stirrups (Longitudinal bars) = 8mm |
No. of Bars used | 1. Main bars = 4 2. Stirrups = 30 |
Cutting length | 1. Main bars = 3.16m 2. Stirrups = 2.64m |
Total Length of bar | 1. Main bars = 18.4m 2. Stirrups = 43.2m |
How do you calculate cutting length of four legged stirrups?
The cutting length of the stirrup-2 : a = [2X + (2nos. × 1/2× dia. of rebar) + (2nos. × 1/2 dia.
How do you estimate stirrups?
Steps involved in finding the cutting length of stirrups
- Look at the size of column or beam from drawings.
- Adopt Dia of the bar (generally 8mm Dia is used for stirrups)
- Deduct the concrete cover or clear cover.
- Find the total outer length of stirrup after deducting concrete cover.
