What thumb rules do you follow while assigning the size of a beam in RCC design of structures?
depth of a beam can be approximately calculated as follows span/12 and breadth=depthX(1/2 to 2/3)
How far can 1.75 x 11.75 Lam beam span without a support?
That depends on what it carries. All joist/beam manufacturers have span tables that will help you determine this.
What do you need to use as a beam to span twenty feet on a deck?
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
How far can you span a 12 steel you-Beam without a support?
Depends on the loads and the properties of the beam. Consult a structural engineer.
What is the relation between density and compressive strength of concrete?
The span to depth ratio is in place preliminary as a method of ensuring deflections falls within certain limits. As concrete is a multi-phase material and does not behave linearly, it is often complex to calculate expected accurate deflections. codes set out given span/depth ratios as a simpler method or ensuring deflections remain in given limits. These ratios have been derived empirically from testing. The compressive strength of concrete as a material does not vary with varying span/depth. However, the amount of the concrete section which is in compression will vary with span and depth due to changes in the applied moment and increase/reduction of the internal lever arm.
I-beam span tables?
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span

What is the span of a beam?
250 Feet
What is the span of a beam bridge?
250 Feet
How do you Calculate yield moment of a concrete beam?
Yield momnet; or the moment at which the concrete beam will fail due to bending can be calculated by:M= (W*L*L)/8Where M= Yield MomentW= weight on beam (Kn usually)L= Span of Beam (M usually)M will be in :Kn per morKn/mhope This helps.
How long can a beam brige span?
250 feet
How far can 1.75 x 11.75 Lam beam span without a support?
That depends on what it carries. All joist/beam manufacturers have span tables that will help you determine this.
What size beam will span 18 feet?
That question cannot be answered without knowing the load on the beam.
How do you size beam by span?
first you need to calculate the load on the entire floor. Different uses mean different loads, you look that up in the building code. Then you calculate how much of the floor is held up by the beam. Then you look up what size of beam to use for the number of pounds per lineal foot. For 1 or 2 family homes you can have a lumber yard do this for you. For commercial construction it has to be done by an architect or an engineer.
What do you need to use as a beam to span twenty feet on a deck?
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
What is a continuous span?
two beam bridges linked together
27 foot span what would you need for a beam?
Span/load beam questions really cannot be answered. You will need to have the plans looked at by a engineer. At the very least the lumber yard selling the beam may have an on-staff engineer to have a look at it.
