bar cranking is the process of bending up the bottom steel bars in upward direction. it is mainly to prevent upward bending moment near the joint. also useful for attaching stirrup bar efectivly. cranking is also used in two way slabs

The prefix 'T' signifies a ribbed bar profile. This is as opposed to a bar with an 'H' prefix which has a smooth profile.
Rebar is an informal term for steel "reinforcing bar". These are steel bars that are placed within the structure before the wet concrete is placed. Steel reinforcement is necessary for almost all structural concrete because concrete has virtually no tensile or shear strength. The rebar provides almost all of the resistance to tension and shear within the structure.
the density of TMT R/F steel is 7850

Yes.A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is given ridges for better mechanical anchoring into the concrete. It can also be described as reinforcement or reinforcing steel. In Australia, it is colloquially known as reo.To know more about rebar visithttp://en.wikipedia.org/wiki/Rebarhttp://www.rgsrebar.com
Unit weight of 22mm dia reinforcement steel bar is 3 kg per metre length - Answer by m. Velsamy mobile 09884585625
if the bar length is 5o m , what will be the actual length including lap length
The numbers refer to the different diameters of the rebar used to reinforce the concrete. R specifies round bar. Y or N specify deformed bar. See below. == * Round mild steelreinforcement bar - R6 R10 R12 R16 R20 R24 R28 R33 * Deformed reinforcement bar - N12 N16 N20 N24 N28 N32 N36 * Stock lengths of reinforcement bar - up to 12 metres * S12 Pool Steel - Mild steel bars (not tempcore) that is very easy to bend by hand * Processed reinforcement bars - custom cut and bent to required needs * Dowel Bars - precut, often galvanised round bars used when one slab joins another * Galvanising - Plain Reinforcement Steel bars can also be supplied galvanised *Deformed Bar was previously called Y-Bar eg: Y12, Y16 but through product improvements the tempcore strength was increased (now 500Mpa) and is now denoted as N-Bar as listed above
The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
If I under stand your question correctly, you are asking a technical question : What is CRS bar? CRS is Corrosion Resistant Steel reinforcement bars used in Reinforced Cement Concrete. This is not as good as Stainless steel, but better than ordinary Reinforcement bars and is manufactured by some manufacturers like Tata Steel (in India) by giving some surface chemical treatment to the bars. Trust this answers your question.
Reinforcement is anything that provide additional strength to a beam. In a standard beam reinforcement refers to steel bars.
Under reinforcement is safe because in this case steel fails before concrete.
