Why do we need to put temperature bars in one way slabs?

Slabs are large flat concrete members that may be exposed to the sun. Examples of which are pavement, roads, basketball courts, sidewalks, etc. When concrete expands, you need rebar to stop it from breaking since concrete is not very good in tension.

What is the purpose of temperature bars?

Steel rods placed horizontally in concrete slabs for prevention of cracks due to temperature changes or drying; placed parallel to the reinforcing rods. The steel rods are placed at right angles to the main reinforcing bars.

What is shrinkage reinforcement?

In reinforced concrete, steel reinforcement which is designed to resist shrinkage stresses.

What are temperature bars and shrinkage bars?

Steel reinforcement which is designed to resist shrinkage stresses is called shrinkage or temperature reinforcement. Shrinkage and temperature reinforcement requirements for design of reinforced concrete structures have been included in the ACI building code since 1928, and haven’t changed much in nearly 75 years.

Under what circumstances you go for a one-way slab?

If the L/b ratio is greater than or equal to 2 or then it is considered a one-way slab. If the L/b ratio is less than 2 then it is considered a two-way slab.

What is shrinkage and temperature reinforcement?

What is a shrinkage bar concrete?

RE: What is ‘shrinkage bar’ in concrete beam??? Temperature and shrinkage reinforcement is used to restrain development of cracks and decrease crack width due to both initial drying and curing shrinkage, and those due to thermal cycling and similar phenomena.

What is the implication of shrinkage to a structure?

Shrinkage does have a valuable aspect in the case of reinforced concrete in that it causes the concrete to grip the steel tightly thus reducing the possibility of bar slippage. The size of cracks formed by shrinkage of concrete can be reduced by the use or shrinkage reinforcement.
