For this general thumb rule, we will assume a structure of G+1 floors high, using standard 6″ walls. Minimum size of an RCC column should not be less than 9” x 12” (225mm x 300mm) with 4 bars of 12 MM Fe415 Steel. These days the minimum I use in my projects is 9″ x 12″ (225 mm x 300mm) with 6 bars of 12 MM Fe500 steel.
7.5 m
Beside this, What is the maximum height of column?
24 m.
Likewise, What is the minimum and maximum distance between two columns?
The Minimum Spacing or Distance between two column should not be less than 2.5 Meter. It Must be 2.5 Meter minimum distance. Or, Maximum Spacing & Distance of two Columns Should not be less than 7.5 meter.
Also, What is the maximum height of concrete casting?
10 to 12 feet
What is the maximum distance between two columns?
The maximum span between columns for normal structures is 7.5 m and minimum spacing is 2.5 m.

What is the standard size of beam?
225 mm × 300 mm
How do you calculate beam size?
The formula for the section modulus is beam width times beam depth squared divided by 6. A two 2-by-6 standard beam has actual dimensions of 1.5-by-5.5 inches which would give a section modulus of 1.5 x 5.5 x 5.5 / 6 = 7.6 which is not enough for this example. A 2-by-8 beam would be sufficient.
What is the standard length of I beam?
4-12 m
What is the standard size of column for 2 storey house?
230mm x 300mm
What is the maximum height through which concrete can be poured?
10 to 12 feet
What size beam do I need to span 14 feet?
According the charts I have, you would need a 6×12 beam on each side to support 7680 pounds over a 14′ span (assuming you want less than a 1/360 deflection).
What is the maximum length of beam?
The 6m span comes from practical experience for most engineers. I myself always avoid using beams with 5.5m and above span. However, If the beam is reinforced with prestressed steel, there is no problem to go for longer spans.
What lengths do steel beams come in?
Available in 6, 8, 9.2, 9.5, 10.3, 11, 12.2, 12.5, 13, 14, 15.3, 15.5, 16 & 18 Metre (although not in all sizes) lengths and commonly in Grades 43A & 50D.
How big of a beam do I need to span 24 feet?
You’ll need at least a 12″ (nominal) I-joist or an engineered floor truss to span that far, or you’ll need an LVL or steel beam midway.
How long can a beam span?
When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2×12 beam can span 12 feet; a (2) 2×10 can span 10 feet and so on.
How far can a steel I-beam span?
The taller the beam, say 10 or 12 inches rather than 8 inches, the greater the distance you can span between support posts. I had spans as great as 14 feet in my own basement using the 10×31 steel beams. Heavier beams can sometimes span greater distances between posts.
