What is the maximum span of beam without column?
Steel beam can span 20/30 m depending on the section size. As a rule of thumb the depth of beam should be 1/20th of the span based on deflection limit. That means if you are planning for for 10m span you might be looking for a steel beam with depth up to 500 mm.
How big of a beam do I need to span 18 feet?

What happens if beam spans are too long?
There is no limitation for the length of a beam unless some factors are presumed. We can have any span for the beam. When the span increases, there will be problems with excessive deflections which leads to large bending moments and shear forces.

How far can concrete beam span?
150mm – ‘Standard concrete Beam’
The clear span at maximum spacing in a standard domestic application is 4671mm.
How do you calculate beam size?
Calculate the maximum bending moment for the wooden beams. The bending moment is the length of the span times the weight to be supported divided by 8. For a beam spanning a 12-foot room and supporting a weight of 600 lbs., the maximum bending moment would be 12 x 600/8 = 900 foot-pounds.
What is supported length of beam?
A beam’s length represents the total length of the entire modeled assemblage including any overhanging length on the outside edges of the supports. This value is typically entered in first and must accommodate the length of the opening above which the beam is spanning as well as the bearing plates on either side.
What size beam do I need for a 24 foot span?
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 …
