Weight of square hollow section steel

Weight of square hollow section steel

Square hollow section steel is a commonly used structural steel in civil engineering projects. It is known for its strength, durability, and versatility, making it suitable for a wide range of applications. One of the key factors in determining the suitability of square hollow section steel in a particular project is its weight.

The weight of a square hollow section steel is determined by its dimensions, which include the length, width, and thickness. The weight per unit length of a square hollow section steel is calculated by multiplying the cross-sectional area by the density of the steel. The density of steel varies depending on its composition, but as a general rule, it is around 7850 kg/m3.

The cross-sectional area of a square hollow section steel can be calculated using the formula A = (D- t)², where D is the outer diameter, and t is the thickness of the steel. This means that the thicker the steel, the higher the weight per unit length. However, the weight of a square hollow section steel is not only affected by its thickness but also by its length. The longer the steel, the heavier it will be.

To get the total weight of a square hollow section steel, its weight per unit length is multiplied by its total length. This weight is usually expressed in kilograms (kg) or tonnes (t).

For example, let’s say we have a square hollow section steel with dimensions of 100mm x 100mm and a wall thickness of 5mm. Using the formula above, we can calculate its cross-sectional area as follows:

A = (100 – 5)² = 95² = 9025mm²

Converting this to m², we get 0.009025m². Now, to calculate the weight per unit length, we need to multiply the cross-sectional area by the density of steel, which is 7850 kg/m³.

Weight per unit length = 0.009025m² x 7850 kg/m³ = 70.7425 kg/m

If we were to use a length of 10m, the total weight of this square hollow section steel would be:

Total weight = 70.7425 kg/m x 10m = 707.425 kg

Square hollow section steel is also available in different grades, which affects its weight as well. For example, high-strength steel will weigh more than low-strength steel with the same dimensions.

In conclusion, the weight of square hollow section steel is an important factor to consider in civil engineering projects. It is determined by the dimensions of the steel, its thickness, and its length. The weight of steel plays a crucial role in the design and construction of structures, and engineers must carefully calculate and consider it during the planning phase of a project.

■ what is admixture of concrete and its types

Admixtures are a type of chemical ingredients that are added to concrete in order to improve its properties and performance. They are used to alter the composition of the concrete mixture and provide specific characteristics to the hardened concrete. Admixtures are used in combination with cement, water, and aggregates to produce concrete that is strong, durable, and workable.

There are various types of admixtures available in the market, each serving a specific purpose in concrete construction. Here are some of the common types of admixtures used in concrete:

1. Accelerators
Accelerators are used to speed up the rate of concrete setting and hardening. They are typically used in cold weather conditions when concrete may take a longer time to set. Accelerators are also useful in high-traffic areas where the concrete needs to be ready for use quickly.

2. Retarders
Retarders, on the other hand, delay the setting process of concrete, making it more workable for a longer period of time. Retarders are often used in hot weather conditions where concrete can set too quickly, or in large construction projects where there is a need to transport concrete for a longer distance.

3. Water-reducing admixtures
Water-reducing admixtures, also known as superplasticizers, are used to reduce the amount of water needed in the concrete mixture. This results in a higher strength and more workable concrete. Water-reducing admixtures are commonly used in high-strength concrete, self-compacting concrete, or in situations where the concrete needs to be placed in difficult-to-reach locations.

4. Air-entraining admixtures
Air-entraining admixtures are used to create microscopic air bubbles in the concrete mixture. These bubbles provide resistance to freezing and thawing, preventing the concrete from cracking in cold weather conditions. Air-entraining admixtures are also useful for improving workability and reducing bleeding in concrete.

5. Pozzolanic admixtures
Pozzolanic admixtures are used to reduce the heat of hydration in concrete, thereby preventing thermal cracks. They are also effective in increasing the durability of concrete and reducing the permeability of the concrete, making it more resistant to chemical attack and water penetration.

6. Corrosion inhibitors
Corrosion inhibitors are used to protect the steel reinforcement in concrete from corrosion. They work by forming a protective coating on the surface of the steel reinforcement, preventing it from coming into contact with water and other corrosive agents.

7. Shrinkage reducing admixtures
Shrinkage reducing admixtures are used to reduce the drying shrinkage of concrete, which can lead to cracking. These admixtures are particularly useful in large concrete placements, where cracking can be a significant problem.

Overall, admixtures play a crucial role in the improvement of concrete properties, making it more workable, durable, and resistant to various external factors. However, it’s important to note that the effectiveness of admixtures depends on the quality and proportion of the materials used, proper application, and adherence to recommended dosage rates. Therefore, it is essential to consult with a qualified engineer or supplier before using any admixture in concrete construction.

Steel weight formula

Steel weight formula

Steel weight formula is a mathematical equation used to calculate the weight of steel bars or structural shapes. This formula is widely used by civil engineers in the design of various structures, such as buildings, bridges, and tunnels, as it helps determine the amount of steel required for the project.

The formula for calculating the weight of steel is W = D2L/162.2, where W is the weight in pounds, D is the diameter of the steel bar or shape in inches, and L is the length of the steel bar or shape in feet. This formula is based on the assumption that the density of steel is 0.2836 pounds per cubic inch.

For example, if a steel bar has a diameter of 1 inch and a length of 10 feet, the weight can be calculated as follows:
W = (1)2(10)/162.2 = 0.06157 pounds per foot
Therefore, the weight of the steel bar is 0.06157 x 10 = 0.6157 pounds.

One important thing to note is that this formula applies to mild steel only. For other types of steel, such as stainless steel, the density and weight calculation will vary.

In structural steel design, engineers also use another formula to calculate the weight of beams and columns. This formula takes into account the shape of the steel and is often referred to as the cross-sectional method. The formula is W = A x L x C, where A is the cross-sectional area of the steel shape in square inches, L is the length of the steel in feet, and C is a coefficient determined by the shape and profile of the steel beam or column.

Another useful formula for calculating the weight of steel plates is W = L x W x T x C, where L is the length of the plate in inches, W is the width of the plate in inches, T is the thickness in inches, and C is the density of steel in pounds per cubic inch.

In addition to these formulas, there are also online calculators and software programs available to help engineers quickly and accurately calculate the weight of steel.

In conclusion, the steel weight formula is an essential tool for civil engineers in the design and construction of various structures. It enables engineers to determine the amount of steel needed for a project, helping to optimize design and reduce construction costs.
