how to calculate axial load on column

Columns play a significant role in supporting weight in construction. The load that they bear is known as the axial load. Axial load is the force that is applied in a straight line along the center of the column. As the load on the column increases, the stress on the column also increases. Therefore, calculating the axial load on a column is essential to ensure its strength and stability.

Factors affecting axial load

The axial load on a column is influenced by several factors. The first factor is the weight of the structure that the column is supporting. The larger the weight of the structure, the greater the axial load. The second factor is the height of the column. As the column height increases, the axial load also increases. Another factor is the material used in constructing the column. Different materials have varying capacities to carry load. Finally, the type of connections used to connect the column to the rest of the structure affects the axial load.

Calculating Axial Load on A Column

To calculate the axial load on a column, we need to consider several factors. Firstly, we need to know the cross-sectional area of the column. This area is measured in square inches or square meters, depending on the units used. Secondly, we need to determine the load per unit area. This load can be calculated by dividing the weight of the structure by the cross-sectional area of the column. Finally, we need to multiply the load per unit area by the total cross-sectional area of the column to get the total axial load.

Example Calculation

Suppose we have a column made of concrete, with a cross-sectional area of 10 square inches and a length of 12 feet. The structure that the column supports has a weight of 50,000 pounds. To calculate the axial load on the column, we first need to determine the load per unit area. This is done by dividing the weight of the structure by the cross-sectional area of the column as follows:Load per unit area= 50,000 pounds/ 10 square inches= 5,000 pounds per square inchNext, we multiply the load per unit area by the total cross-sectional area of the column as follows:Axial load= 5,000 pounds per square inch × 10 square inches= 50,000 poundsTherefore, the axial load on the column is 50,000 pounds.

Conclusion

Calculating axial load on a column is vital to ensure that the column can support the weight of the structure it holds. The calculation takes into consideration the cross-sectional area of the column, the load per unit area, and the total cross-sectional area of the column. This calculation is essential to ensure the structural integrity of buildings and to guarantee the safety of occupants.
