What is Stirrup:
A stirrup (Used in Beams) is a closedloop of rebar used to hold the main bars in an RCC structure together. Stirrups provide lateral support to the main bars against buckling.
Stirrups are used to provide reinforcement in concrete beams, which helps prevent cracks from forming. They are primarily used to transfer forces through tension, bending, and shear. The space between the stirrups varies along the length of the beam. The stirrups are spaced close together near the supports, and farther apart in the middle section. Cutting Length Formula for Reinforcement, cutting length of stirrups, calculate cutting length
What is Lateral Ties:
Lateral ties (Stirrups in Column) help hold the position of reinforcing steel in columns without disturbing the concrete space. cutting length of stirrups
The vertical steel bars in a concrete column are responsible for holding up the building’s weight, while the wire ties help keep each bar in place as the concrete sets around it. The ties, which do not take part in supporting the load of the building, are evenly spaced along the full height of the column. Calculate cutting length, total bend length, bar bending schedule Cutting Length Formula for Reinforcement
Difference Between Stirrups and Lateral Ties:
Lateral ties and stirrups are both used to reinforce beams and columns. The only difference is where they are placed. Lateral ties are placed in a column, while stirrups are attached to a beam. They both serve the same purpose: to reinforce the structure of a building.
Stirrups are commonly made in a rectangular or square shape, but they can be circular or diagonal as well. calculate the cutting length, stirrups cutting length, stirrup bar, civil engineers
Purpose of Stirrups in Reinforcement:
There are the following purpose to provide stirrups in beam or column reinforcement:
In Beam:

To provide ductility to section, i.e., to prevent diagonal cracks from forming and possibly leading to abrupt failures. civil engineering, single legged stirrups

To resist any torsion or twisting. different shapes, deducting concrete cover

To prevent the growth of inclined shear cracks. However, even when the shear stress is less than half of the concrete’s shear resistance (but greater than half of shear resistance )

To increase the stability of dowels. different shapes, cutting length of stirrup
Stirrups can be provided as open stirrups or close stirrup. However in doubly reinforced sections and to resist torsion closed stirrup is mandatory. In doubly reinforced section closed stirrup performs the additional function of preventing buckling of compression reinforcement and confining concrete. construction work, open stirrup, length of stirrup
One more thing, stirrups are usually tied in compression side to improve anchorage and to avoid crack initiation. two hooks, length of the hook, circumference, pythagoras theorem
In Column:
Lateral Ties or Stirrups in columns are provided to perform following functions:

To restrain longitudinal bars from moving sideways

To provide resistance against shear and torsion.

To hold longitudinal bars during construction.

To confine the concrete in the core, thus improving ductility and strength.

To prevent premature buckling of individual bars. calculate, civil engineer working, on site

Width of Single Stirrup Column Reinforcement C/C = a = [(2 x D) + (2 x Half Dia of Bar) + (2 x Half Stirrups Dia)] Stirrups Length Calculation
Distance between Dowels in XDirection = D = [C/C Distance] / 3
so first of all we should find the C/C Distance;
C/C Distance = Total Width – [ ( 2 x CC ) + (2 x Stirrups Dia ) + ( 2 x Half Dia of Bar) ]
C/C Distance = 400 – [(2 x 30) + (2 x 8) + (2 x 10)]
C/C Distance = 400 – [60 + 16 + 20]
C/C Distance = 304 mm

Total Bend Deduction = 3 x 900 Bend length + 2 x 1350 Bend length
Total Bend Deduction = (3 x 2d) + (2 x 3d) = 6d + 6d = 12d = 12 x 8 = 96 mm
Final Cutting Length of FourLegged Stirrups:
Formula: Total Cutting length of 4Legged Stirrup Formula = 2 x (Perimeter of Rectangle + Total Hook length – Total Bend Deduction)
where we multiply 2 because we have two pieces of rectangular stirrups in 4Legged stirrup
Total Cutt length of 4Legged Stirrup = 2 x (Perimeter + 20d – 12d)
Total Cutt length of 4Legged Stirrup = 2 x (1325.34 + 160 – 96) = 2 x 1389.34
Total Cutt length of 4Legged Stirrup = 2778.68 mm = 2.778 m
Hence the Cutt Length of 4Legged Stirrups is 2.778 m
8Cutting length for Trapezoidal Stirrups:
Trapezoidal stirrups is usually adopted in rectangular shape of column or beam, now we are going to find the cutt length of Trapezoidal stirrups as per the following method:
Size of Column:
Considering the above Rectangular column size 300 mm x 400 mm.
Width of Column = W = 600 mm
Depth of Column = H = 400 mm
Dia of Bar:
Adopting Dia of Bar used for stirrups is,
Stirrup Dia = d = 8mm
Dia of Main Bars (M.B) or Dowel Bars = D = 12mm
Deduction for Concrete Cover:
Usually we use the clear cover for column is 25 mm to 40 mm but here we will use, as per the given figure: clear cover = 40 mm (from all sides)
Bottom side Stirrup Reinforcement = a = W – (2 x CC) – (2 x half Dia of Sturrups Bar)
Bottom side Stirrup Reinforcement = a = W – (2 x CC) – d
Bottom side Stirrup Reinforcement = a = 600 – (2 x 40) – 8
Bottom side Stirrup Reinforcement = a = 512 mm
Top side Stirrup Reinforcement = b = C/C Dist of Main Bar + (2 x half Dia of M.B) + (2 x half Dia of Stirrups Bar)
First of all we find the,
C/C Dist of Main Bars = [W – (2 x CC) – (2 x Stirrups Dia) – (2 x half of M.B Dia)] / 3
C/C Dist of Main Bars = [W – (2 x CC) – (2 x d) – D]/3 = [600 – (2 x 40) – (2 x 8) – 12] / 3
C/C Dist of Main Bars = 492 / 3 = 164 mm
Now,
Top side Stirrup Reinforcement = b = C/C Dist of Main Bar + (2 x half Dia of M.B) + (2 x half Dia of Stirrups Bar)
Top side Stirrup Reinforcement = b = C/C Dist of Main Bar + D + d = 164 + 12 + 8
Top side Stirrup Reinforcement = b = 168 mm
therefore, Length of c = Sqrt( Base2 + Perp2)
where, Base = C/C Dist of M.B + half Dia of stirrups Bar and & Height = H – (2 x CC) – (2 x half Dia of Stirrups Bar)
so first we find the, Stirrups Length Calculation
Base = C/C Dist of M.B + half Dia of stirrups Bar = C/C Dist of M.B + d/2
Base = 164 + 8/2 = 164 + 4 = 168 mm
Height = H – (2 x CC) – (2 x half Dia of Stirrups Bar) = H – (2 x CC) – d = 400 – (2 x 40) – 8
Height = 312 mm Stirrups Length Calculation
Now, Length of c = Sqrt( Base2 + Perp2) = Sqrt(1682 + 3122) = Sqrt(28,224 + 97,344)
Length of c = Sqrt(125,568) = 11.21 mm
so, a = 512 mm and b = 168 mm and c = 11.21 mm
Perimeter of Rectangular Stirrup:
Perimeter of Rectangular Stirrup = a + b + (2 x c) = 512 + 168 + (2 x 11.21) = 512 + 168 + 22.42 = 702.42 mm Stirrups Length Calculation
Perimeter of Rectangular Stirrup = 702.42 mm
Total Length of Hooks:
Hook length should not be less than 75mm and it is different as per the different dia of bars but usually we consider 10d for one hook; Stirrups Length Calculation
Hook’s Length for Stirrups = 2 x 10d = 20d = 20 x 8 = 160 mm
Total Bend Deduction:
As per the above figure, There are 1 bends which are bent at an angle of 450 and 4 bends are bent at an angle of 1350, so as per the bend deduction formula;
Total Bend Deduction = 1 x 450 Bend length + 4 x 1350 Bend length
Total Bend Deduction = (1 x 1d) + (4 x 3d) = d + 12d = 13d = 13 x 8 = 104 mm
Final Cutting Length of Trapezoidal Stirrups:
Formula: Total Cutting length of Trapezoidal Stirrup Formula = Perimeter of Rectangle + Total Hook length – Total Bend Deduction
Total Cutt length of Trapezoidal Stirrup = Perimeter + 20d – 13d
Total Cutt length of Trapezoidal Stirrup = 702.42 + 160 – 104 = 758.42 mm
Total Cutt length of Trapezoidal Stirrup = 758.42 mm = 0.758 m
Hence the Cutting Length of Trapezoidal Stirrups is 0.758 mf Stirrups in Column
