In 2012, the Empire State Building in New York City received a steel I beam spanned between two towers. The beam has been dubbed “the world’s longest” because it is longer than any other beam on its own and forms an angle with both ends at 107 degrees to one another.
The “what size steel beam to span 26 feet” is a question that comes up in many construction projects. One of the most common materials for beams is steel, which can be used to span distances between 26 and 30 feet.
Spans of more than 20 meters are possible (for the purposes of this article the definition of long span is taken as anything in excess of 12 m). Long spans provide flexible, column-free interior spaces, save substructure costs, and speed up steel installation.
How far can a beam stretch without being supported?
A double ply beam may span in feet a value equal to its depth in inches when supporting joists that span 12 feet with no overhang beyond the beam. A double 2×12 beam may span 12 feet, while a (2) 2×10 beam can span 10 feet, and so on.
As a result, I’m wondering how large of a beam I’ll need to span 20 feet. Size of 20-foot clearspan beam To span the 20′, you’ll need something like a 12-16″ GLULAM or LVL, and you can use ordinary 2×8-10 dimensional timber 16″OC as floor joists.
How do you size a steel I beam in this manner?
Measure the distance in inches that the steel beam will need to cover. As your clear span for the beam, write this value down on a piece of paper. The length of the floor joist that the I-beam must sustain in inches. Subtract two from the total.
What is the price of a steel I beam?
Costs of Steel I-Beams Steel I-beams may be found from your local steel supplier. If you just want a single length of I-beam, they may be able to cut you a 6′ or 8′ length from a waste piece left over from a larger shipment. The price per pound will range from $.90 to $1.25.

What is the Maximum Length that a 2×6 beam can span without support?
In general, 16-inch-on-center joists may reach 1.5 times their depth in inches in feet. A 2×8 may be up to 12 feet long, a 2×10 can be up to 15 feet long, and a 2×12 can be up to 18 feet long.
How do you calculate the size of a load-bearing beam?
The section modulus is calculated by dividing the beam width by the beam depth squared by 6. The actual dimensions of two 2-by-6 standard beams are 1.5-by-5.5 inches, giving a section modulus of 1.5 x 5.5 x 5.5 / 6 = 7.6, which is insufficient for this case. It would be sufficient to use a 2-by-8 beam.
What is the maximum weight that a 2×12 beam can support?
About 180 lbs. per foot, or 2,100 lbs., may be supported by a single 2×12.
What is the Maximum Length of a 6×12 beam?
The loading condition is 40 pounds per square foot live and 10 pounds per square foot dead.

How do you calculate the length of a beam?
Design a beam depth by dividing the span by 20 as a rule of thumb for calculating the depth of manufactured beams. 5 1/2 inches, 7 1/4 inches, 9 1/4 inches, 11 1/4 inches, 11 7/8 inches, 14 inches, 16 inches, 18 inches, and 20 inches are common beam depths.

What is the maximum weight that a steel beam can support?
If you have a steel beam with a basic permitted bending stress of roughly 23000 lbs per square inch, the actual bending stress that the beam can sustain under these circumstances is about 6100 lbs per square inch after you account for the span and the absence of constraint.
What kind of bearing does a steel beam require?
Support for the Structure
Any new beam should have at least 150mm of bearing (overlap into the existing wall) on either side of the aperture, and the old wall under the bearings should be reinforced to avoid crushing.
What factors should I consider while selecting steel beams?
How to Choose an I-Beam
- The loading data for the steel I-beam must be specified.
- Create a diagram for the bending moment depending on the information provided.
- Select the steel I-approximate beam’s size.
- Determine the steel I-area beam’s moment of inertia.
- Determine the depth of the beam.

What is a header beam, and what does it do?
A header is a beam that spans a doorway, window, skylight, or stairwell opening. In wood-frame building, the term header now refers to a beam-like support. The header is a cut-out in the ceiling or floor for a skylight, chimney, or stairway, or it spans an opening for a window or door.
What is an LVL beam, exactly?
Laminated veneer lumber (LVL) is a kind of engineered wood that is made up of numerous layers of thin wood that are adhered together. It’s often found in headers, beams, rimboard, and edge-forming material.
How much weight can a 2×6 horizontally support?
The kind of load will also influence how much weight a 2×6 can support on its edge. A 2×4 timber, for example, can easily carry a 4-cylinder engine but not a larger one. A 2×6 on the other hand, can sustain a V8 engine weighing between 600 and 700 pounds.
Which is more powerful, the I beam or the H beam?
An H-beam features a thicker middle web, making it more durable. Because an I-central beam’s web is frequently narrower than an H- beam’s, it can’t withstand as much force. Because the H-beam is frequently much heavier than the I-beam, it can withstand greater force.
