# How do you calculate the load bearing capacity of a steel beam?

## How do you calculate the load bearing capacity of a steel beam?

Solution:

1. Loads on the RCC Slab. Self-weight= concrete unit weight * Volume of concrete. = 24 * 0.1= 2.4 KN/m2
2. Loads on the Beam. Self-weight= concrete unit weight* beam width*beam height. =24 * 0.28*0.25= 1.68 KN/m.
3. Compute Applied Moment. Assume partial fixity of columns.
4. Geometry of the Original Section.

What is the load capacity of a steel beam?

Designation (Width x lbs/ft) Nominal Size – Depth x Width (inches x inches) Allowable Uniform Load (lb)
Span (ft)
W8 x 10 8 x 4 15600
W8 x 13 8 x 4 19900
W8 x 15 8 x 4 23600

### How do you calculate beam load bearing capacity?

Multiply the loading per square foot by the area in square feet of the surface which the beams will be supporting. Divide by the number of beams which will be installed to get the loading per beam.

How big of a steel beam do I need?

To calculate the necessary depth of a beam, divide the span (in inches) by 20. For example, a 25′ span would be 25×12 / 20 = 15”. The width of this beam would be between 1/3 and ½ the depth. The dimensions of a girder would be the same, but the flange would be thicker.

## How do you size steel beams?

It’s easy to select the right size I-beam for your project when you know the load, or weight, that you need the I-beam to bear. Measure the distance in inches that you need the steel beam to fill. Write this figure down on a sheet of paper as your clear span for the beam.

What size beam do I need for a 12 foot span?

A double ply beam can span in feet if there is no overhang beyond it. A double 2×12 beam can span 12 feet, a double 2×10 can span 10 feet, and so on.

### What size beam will span 24 feet?

For 24 foot span, size of simply supported beam for 2-3 storey residential building, using thumb rule, is about 15″×18″ in which beam width is 12″ and beam depth is 15″, if width will be kept 12″, depth should increased, then beam size 12″×24″ can be used, providing with 4nos of 16mm bar at top, 4nos of 20mm bar at …

How do you size a structural beam?

The sizing steps are:

1. determine the total load and live load per foot of beam.
2. identify the type of load you are supporting (roof snow, non snow or floor)
3. pick the span you need.
4. match the total load and live load values to the values listed in the tables. The thickness and depth of the required member will be listed.
