When steel bars are placed on both sides of a concrete beam, one side resists tensile forces and the other side resists compressive forces. The presence of tension or compression on top or bottom depends on the type of structure.

What is the difference between the singly reinforced beam and doubly reinforced beam?
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
What is the difference between inverted beam and drop beam?
An inverted beam is a beam whose bottom is the same as the slab. A drop beam is a beam that is put under the structural member it supports.
Why is the reinforcement bars place at the bottom of the simple supported beam?
When a simply supported beam is subject to bending; the top of the beam will be subject to compression, and the bottom of the beam will be subject to tension (think about the bottom of the beam stretching as it bends i.e. tension). Concrete is strong in compression but weak in tension, so steel reinforcement is added to allow it to resist this tension and carry bending sufficiently. Note: bars are generally added to the compression side too but that's for another day.
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 construction beam?
Almost any solid horizontal structural member is considered a beam. They are usually steel or concrete and are used to transfer a vertical load imposed on the span (middle) of the beam to the ends or vertical supports of the beam. Steel beams are probably what most people think of when picturing a beam. W-sections (formerly known as I-beams, but are modified by the strength/type of steel and the cross section shapes) are the most common steel beams used. Concrete beams are often used in foundations and can be best seen above ground in parking garages everywhere. There is always a good amount of reinforcing steel in a concrete beam to carry the tension that occurs in the bottom of a beam so the concrete won't fracture.

What is the difference between an you beam and a beam?
An 'U' beam is a beam that is shaped like the letter 'U'. It is usually made of 3 parts; 2 sides and 1 bottom piece. A beam would normally refer to an 'I' beam (A beam that is shaped like the letter 'I'). The difference is that cross section of the beams are different.
What is difference between beam and channel?
The channel is U-shaped cross-section, while the crossbeam is can be divided into H-plate, I-beam, etc. Both of them have different uses.

What the difference between ismb and ismc?
ismc-indian standards medium weight channel & ismb-indian standards mild steel beam there is only diff of flendge.
What is the difference between a beam and a column?
A beam will be placed horizontally, a column will be placed vertically.
What is the difference between a column and a beam?
A beam will be placed horizontally, a column will be placed vertically.
Difference between T-beam and rectangular beam?
Dasign of T- beam is some what similar to rectangular beam, in design slab thickness is determined first. the slab is acts as compression flange in designing the beam. the flange acts as compression zone, which is balance by steel embeded in the bottom web of the beam. slab thickness= t, in. effective depth= d, in. width of web= b', in. flange width= b, in. width of flange should be least of the three alternatives, 1. span/4. 2. b' + 16t. 3. centre to centre spacing of beams.
What is the difference between a beam and a bar?
Beam can take transvesr loading and bar only axial loading
