Types of Stirrups Used in Reinforcement

Stirrups

Stirrups is an steel reinforcement bars (rebar) shaped into closed loops, typically used in reinforced concrete footing, Column, beam & slabs. They are positioned perpendicular to the longitudinal reinforcement bars and are tied to them to create a cage-like structure.

Stirrups provide lateral support for longitudinal reinforcement to prevent the buckling & improving the shear resistance of the concrete.

stirrups are designed to resist shear forces and to hold the main reinforcement bars also providing stability & Prevent the crack from heavy loads Shape of stirrups designed based on the structure

Based on shape its classified in following types

Square Stirrups
Rectangular Stirrups
Triangular Stirrups
Diamond Stirrups
Circular Stirrups
Spiral (or) Helical Stirrups

Based on the number of vertical bars or legs classified in following types

Single legged Stirrups
Two legged Stirrups
Four legged Stirrups
Six legged Stirrups

Square Stirrups

Square stirrups are commonly used in structural elements with square cross-sections in residential, commercial, and industrial buildings.

But these kind of stirrups are highly effective specific structural situations.

these stirrups are typically used in triangular or trapezoidal beams and load-bearing members

Triangular stirrups has good shear resistance and are especially useful in structures with unconventional shapes or design constraints.

Minimum Number of Bars: 3 longitudinal bars

Diamond Stirrups

Diamond-shaped stirrups, are used in construction where the column & beam required non standard cross section.

Due to this shape its called as diamond shape stirrups, these diagonal shapes provides shear resistance and lateral support to the structure.

This type stirrups also used in less commonly to compare other types.

Minimum Number of Bars: 4 longitudinal bars

Circular Stirrups

Circular stirrups are used in the construction of round columns, piers, and piles.

These circular shape distribute the load equally around the circular cross-section to prevent the crack under the high high compressive forces or loads.

Circular stirrups are commonly used in industrial structures, bridges, and high-rise buildings where circular columns are designed.

Minimum Number of Bars: 6 longitudinal bars

Spiral (or) Helical Stirrups

Spiral (or) helical stirrups are designed commonly cylindrical columns or piers where designed.

These stirrups are a continuous steel reinforcement that surrounds the vertical bars in a spiral Arrangement its provides additional support to the structure.

These stirrups used to improve the load bearing capacity & ductility of the structure, particularly under seismic loads or in high-rise buildings.

Single-Legged Stirrups

These Single legged stirrups have an one vertical leg, its not commonly used in concrete structure, They provide minimal reinforcement and are mainly for light structures.

Two-Legged Stirrups

These double legged stirrups have an two vertical leg in both side, these stirrups mostly used in where medium shear reinforcement is required.

Four-Legged Stirrups

These four legged stirrups have an four vertical leg, these stirrups is an most common type of stirrups, its designed for where we need more lateral strength.

Six-Legged Stirrups

These six legged stirrups have an six vertical leg, these type of stirrups are used in heavily loaded column & beams. such as high-rise buildings, bridges, etc..

Why Bitumen Coating is applied for Footing & columns

Bitumen painting is especially common in Basement foundations such as (column and footing & PCC), Retaining walls, Underground structures such as under ground water tank, septic tank, sewage tank, etc. & Areas with high water tables or flooding risks.

There are several reasons behind the application of bitumen coating on footings and columns. The following factors are important

1. Waterproofing

2. Protection Against Chemical

3. Anti-corrosion for Reinforcement

4. Improved Durability

5. Adhesion Enhancement

1. Waterproofing

Bitumen is a hydrophobic material. Its makes a protective barrier that helps prevent water penetration to footings and columns. Waterproofing is necessary in areas where the sea level is high. This is especially crucial in areas where the footing may be exposed to groundwater or moisture.

2. Protection Against Chemical

Also Bitumen is protect the footing & Columns from the harmful chemicals present in the soil, Those chemicals may make some corrosion the concrete or steel reinforcement, such as chlorides or sulfates.

3. Anti-corrosion for Reinforcement

Bitumen also protects the reinforcement steel from corrosion due to moisture ingress. This is important in maintaining the strength and load-bearing capacity of the footing.

4. Improved Durability

The coating helps to increase the durability of the foundation (Column, Footing, PCC) by protecting from environmental factors such as moisture, salts, and acids in the soil, It helps prevent the weakening of the footing.

5. Adhesion Enhancement

Also one important factor for bitumen coating applied on footing or column, Bitumen improves the bond between the concrete surface of the footing and other materials, such as waterproof membranes, protective layers, or soil.

Other alternatives to bitumen include

Epoxy coating
Polyurethane coatings
Acrylic coatings
Cement-based coatings

APPLICATION METHOD OF BITUMEN FOR FOOTING & COLUMN

1. Surface Preparation :- Clean the footing & column surface remove dust & loose particles form the footing & Column

2. Priming :- Heat the bitumen (if it’s a hot-applied bitumen) if For cold-applied bitumen, no heating is necessary, Apply the bitumen through brush, roller or spray as convenient method as per site condition. Make-sure that all edges and surfaces covered with bitumen.

3. Layering :- if the project specification is mentioned that multiple layer bitumen coating, every layer should be applied after completely dry that the old layer.

4. Drying Time & Inspection :- Allow the bitumen coating to dry and cure properly, Drying time may vary depending on the environment condition. typically its takes 16 to 48 hours, After drying, inspect the coating for any missed spots or uneven areas. If necessary, reapply bitumen to ensure complete coverage.

How to calculate the Volume & Surface area of Rectangular Column / Volume Of Concrete / Area Of Shuttering / Area Of Painting work

The following Article explain you that brief explanation of calculation of surface area & volume of rectangular column, surface areas used to find painting & Shuttering areas quantities, also Volume of rectangular is used to find the concrete quantities.

Surface Area calculation / Area of Shuttering / Area of Paint for rectangular column

The surface area of a column refers to the total area that is exposed on the exterior of the column. In the context of a column, surface area typically includes both the lateral surface area (the sides of the column) and the base area.

Surface area = Total Perimeter x Height

What is Perimeter

The perimeter of a rectangle is the total length of its boundary or the sum of the lengths of all its sides. For a rectangle, which has two pairs of equal and opposite sides, the perimeter (P) can be calculated using the formula:

Perimeter =2 X (length + width)

For Example as per above drawing

Length = 600 mm / 0.60 m

Width = 400 mm / 0.40 m

Height = 5.00 m

So, Perimeter = 2(0.6+0.4) = 2.00m

Surface Area = Perimeter X Height

Surface Area = 2.00 x 5.00 = 10m²

So, the Shuttering & Painting area of rectangular column is 10 m²

Volume of Rectangular column / Concrete volume calculation for rectangular column

Volume = Area X Height

Area of Rectangle = Length x Width

Area of rectangular column is = 0.60 x 0.40 = 0.24 m²

So, Volume of Rectangular column = Area X Height

Volume = 0.24 x 5.0 = 1.2 m³

Volume of rectangular column / Concrete quantity of Column is = 1.2 m³

How to calculate the Volume & Surface area of Circular Column / Volume Of Concrete / Area Of Shuttering / Area Of Painting work

How to calculate the Volume & Surface area of Circular Column / Volume Of Concrete / Area Of Shuttering / Area Of Painting work

The following Article explain you that brief explanation of calculation of surface area & volume of circular column , surface areas used to find painting & Shuttering areas quantity also Volume of circular is used to find the concrete quantity

Surface Area calculation / Area Of Shuttering / Painting area for circular column

Formula for Surface Area of circular column is = Circumference X Height (h)

Formula for circumference of circle is = 2 π r

So, The Formula for Surface Area of circular column is = 2 π r h

Value of π = 3.14

r – Radius of Column, So, r (radius) = Diameter of column / 2

As per drawing diameter of column = 400 mm

So, r (radius) =400 /2 = 200mm / 0.20 m

h – Height of Column, As per drawing diameter of column = 5.00m

So, the surface area of column is = (2 π r h)

(2 π r h) =2 x 3.14 x 0.20 x 5.00 = 6.28 m²

Total Surface Area / Painting Area / Shuttering area of Column is = 6.28 m²

Volume of Circular column / Concrete volume calculation for circular column

Volume = Area X Height

Area of circle = πr²

So, Volume of circular column = πr²h

So π=3.14, r=0.20 m & h = 5.0m

πr²h = 3.14 x 0.20 ²x 5.0

Volume of Circular column / Concrete quantity of Column is = 0. 628 m³

How to calculate concrete Volume for Rectangular, Square & Circular Column

Constructing columns is a crucial aspect of building structures, and accurately calculating the concrete volume is essential for a successful construction project. Whether you’re working on rectangular, square, or circular columns, the process involves some straightforward mathematical formulas.

Volume Calculation for Circular column

Volume of Concrete = Cross Sectional Area X Height (h)

Cross sectional Area = πr2

As per drawing diameter (d) = 400 mm / 0.40 m

So, Radius (r) = d/2 =400 /2 = 200 mm / 0.20m

Cross sectional Area (πr2)= π x 0.20², (π = 3.14)

Cross sectional Area = 3.14 x 0.20² = 0.1256 m² (Square meter)

Volume of Concrete = 0.126 m² X Height (h)

As per drawing Height (h) = 5.00 m

So, Volume of Concrete is = 0.126 x 5 m² = 0.628 m³ (Cubic meter)

Volume Calculation for Rectangular column

Volume of Concrete = Cross Sectional Area X Height (h)

Cross sectional Area = Length (L) X Breath (B)

As per drawing L= 600 mm / 0.60 m & B= 400 mm / 0.40 m

Cross sectional Area = 0.60 x 0.40 = 0.24 m² (Square meter)

Volume of Concrete = 0.24 m² X Height

As per drawing Height (h) = 5.00 m

So, Volume of Concrete is = 5 x 0.24 m² = 1.2 m³ (cubic meter)

Volume Calculation for Square column

Volume of Concrete = Cross Sectional Area X Height (h)

Cross sectional Area = Length (L) X Length (L)

As per drawing L= 400 mm / 0.40 m

Cross sectional Area (L X L)= 0.40 x 0.40 = 0.16 m² (Square meter)

Volume of Concrete = 0.16 m² X Height

As per drawing Height (h) = 5.00 m

So, Volume of Concrete is = 5 x 0.16 m² = 0.80 m³ (Cubic meter)
