In the civil engineering field, we need to calculate the possible loads on the column during the design of the columns.

Before calculating the total loads on the

## Types of loads on the column

- The self-weight of the columns.
- The Self-weight of the beams measured per running meter
- Load of the walls measured per running meter
- Total Load of a slab (Dead load, Live load, and Self-weight of a slab)

The bending moments are also present in the column which is considered at the final design.

You can use software like **ETABS or STAAD Pro** for advanced structural design. This software is easy to use and user-friendly tools are available for structural design, and highly recommended.

During structural load calculation, we use *some basic assumptions*.

*Note: These assumptions are used in the calculation process below.*

**The self-weight of Concrete is 2400 kg/m³, which is equivalent to 240 kN.****Self-weight of Steel is 8000 kg/m³.****The density of bricks 2000 kg per cubic meter.**

## 1. **For Columns:**

Let us assume a column of size *400 mm x 400 mm* in dimension.

Height of column *10ft* and assume it contains 1% steel. Then, the self-weight of column is near around *1000 kg/floor*, is equivalent to *10 kN*.

Basically, in the calculation process, we can assume the self-weight of the column between **10 to 15kN per floor.**

## 2. **For Beams**

Let us assume the dimensions of 400 mm x 450 mm excluding slab thickness. The self-weight can be around **3**** kN** per running meter.

## 3.**For Walls**

Let, the thickness of wall = 9 inches (9″)

Height of wall = 3 meter height and

Length = 1 meter,

For a 1 meter long wall, the euivalent weight is = 0.150 x 1 x 3 x 2000 = 900 kg which is equivalent to **9 kN/meter.**

This is the load per running meter of a brick wall.

By using machine-made hollow brick or hollow block you can reduce the wall loads per running meter can be as low as **4 kN/meter for construction**, which helps to reduce the building construction cost.

## 4. **For Slab**

Let’s assume, the thickness of slab = 125 mm.

For each square meter slab the self-weight of slab = 0.125 x 1 x 2400 = 300 kg, equivalent to 3 kN.

Now, always assume the Finishing load as 1 kN/m

and

imposed, live load = 2 kN/m.

So, we can calculate slab load to be around **6 to 8 kN/m².**

**Factor of Safety** for column

Don’t forget to add the factor of safety in loads of column. And don’t add more because it will increase the cost of construction. Form I*S 456:2000*, the **factor of safety is 1.5.**

According to the importance of construction, the factor of safety may be increased or decreased as per requirement.

Always follow IS 456:2000 code during the calculation.

The above-mentioned data are may not as per IS code. We just try to provide you information about the best way to calculate the total loads on a column in an easy method.
