Ever wondered how the depth of a beam is calculated or is there any standard for its calculation?
Yes, of Couse there is a formula to calculate it per ACI (American concrete institute)
Depth of a beam (in inches) = Length of a beam in Feet
For example, if the length of a beam is 12 feet then depth should be minimum 12 inches.
However, it should be noted that this rule also has an exception for example load, spacing requirement, structure condition, etc. therefore it is important to hire a licensed structural engineer before its final computation.
