When constructing a building, it is important to accurately determine the weight of the structure in order to ensure its stability and safety. One of the most crucial components of this weight calculation is the dead load of the brick wall. This refers to the weight of the brick wall itself, as well as any other materials and fixtures it supports. In this article, we will delve into all the factors that determine the dead load of a brick wall and how to calculate it accurately. Understanding this concept is crucial for architects, engineers, and builders alike, and can greatly impact the success and longevity of a structure.

## Various types of load acting on column

Columns are structural elements used in the construction of buildings and structures to support the weight of the structure above it. These vertical members are subjected to various types of loads during their lifespan. Understanding the different types of loads acting on columns is essential in designing and constructing a safe and stable structure. Here are the various types of loads that can act on a column:

1. Gravity loads:

These are the most common types of loads acting on columns. They include the self-weight of the column, the weight of the structure above it, and any other permanent loads such as fixtures, finishes, and equipment. These loads are always acting downward and are transferred to the foundation through the column.

2. Axial loads:

Also known as compressive loads, they act along the axis of the column and tend to shorten the column. These loads can be caused by the weight of the structure above, wind loads, or seismic activity. Columns are designed to withstand these compressive forces and prevent buckling or failure.

3. Lateral loads:

Lateral loads act on the column perpendicular to its axis, causing it to bend or deflect. These loads can be caused by wind, earthquake, or eccentric loading. Columns must be designed to resist these lateral forces to prevent excessive deflection and potential failure.

4. Torsional loads:

These are twisting forces that act on the column around its axis. Torsional loads are less common in columns but can occur due to eccentric loading, asymmetric geometry, or seismic activity. The column must be designed to resist these twisting forces to prevent any structural damage.

5. Thermal loads:

Thermal loads are caused by the expansion or contraction of the column due to changes in temperature. These loads can cause stress and strain in the column, leading to cracking or failure. Proper consideration must be given to thermal loads in the design of columns, especially in structures with extreme temperature changes.

6. Dynamic loads:

Dynamic loads are forces that act on the column due to vibration, impact, or sudden movements. They can result from moving loads, such as vehicles or machinery on a bridge, or from seismic activity. Dynamic loads can cause fatigue in the column, leading to failure if not properly considered in the design.

7. Soil loads:

Columns transmit all the loads above to the foundation, which then transfers them to the soil. The soil must be able to support and resist these loads without excessive settlement or deformation. The type and strength of the soil must be considered in the design of columns to ensure stability and safety.

In conclusion, columns are subjected to various types of loads during their lifespan, and they must be designed to resist these loads to ensure the stability and safety of the structure. Proper consideration of these loads is essential in the design and construction of columns to ensure a long-lasting and durable structure.

## How to calculate dead load of brick wall

Dead load is defined as the weight of all permanent structures and materials that contribute to the overall weight of a building or structure. In civil engineering, it is a crucial factor to consider in the design of any structure as it directly affects the stability and strength of the building. In this article, we will discuss how to calculate the dead load of a brick wall.

1. Determine the dimensions of the wall: The first step in calculating the dead load of a brick wall is to accurately measure and determine the height, length, and thickness of the wall in meters or feet. This information is necessary for the next step in the calculation process.

2. Calculate the volume of the wall: To calculate the volume of the wall, multiply the height, length and thickness of the wall. The result will be the total volume of the brick wall in cubic meters or feet.

3. Find the weight of one brick: The weight of a brick varies depending on its type, size, and density. Therefore, it is essential to find the weight of one brick in kilograms or pounds to determine the weight of the entire wall accurately. This information can be obtained from brick manufacturers’ specifications or by weighing a few bricks yourself.

4. Calculate the number of bricks in the wall: The next step is to calculate the number of bricks in the wall. This can be done by dividing the total wall volume by the volume of one brick. The result will give you the number of bricks in the wall.

5. Determine the weight of mortar: Mortar is the material used to hold bricks together. The weight of mortar can be calculated by multiplying the volume of the wall by the mortar’s density. The density of mortar varies depending on the type of mortar used.

6. Calculate the weight of the wall: The weight of the brick wall can be determined by adding the weight of bricks and the weight of mortar. This will give you the total dead load of the wall.

Alternatively, you can use the following formula to calculate the dead load of the brick wall:

Dead Load = (Volume of wall x Weight of one brick) + (Volume of wall x Weight of mortar)

Finally, it is important to note that the dead load of a brick wall is only one component of the overall dead load of a structure. Other elements such as the weight of the foundation, roof, floors, and other permanent fixtures also contribute to the dead load.

In conclusion, calculating the dead load of a brick wall is a crucial step in the design of any structure. It ensures that the building is constructed to a safe and stable weight-bearing capacity, preventing any potential structural failure.

## Conclusion

In conclusion, understanding and accurately calculating the dead load of a brick wall is an important aspect of the design and construction process. It not only ensures the structural integrity of the wall, but also contributes to the overall stability and safety of the building. By following the methods and factors mentioned in this article, architects, engineers, and builders can effectively calculate the dead load of a brick wall and make informed decisions during the design and construction stages. It is crucial to regularly review and revise the dead load calculations throughout the lifespan of the building to account for any changes or additions. With proper calculation and consideration of the dead load, we can ensure the longevity and functionality of brick walls in buildings.
