The concept of Clear cover and nominal cover is seen in the Reinforced concrete structures.
Reinforced concrete structures have been main structural materials for over a century and still the most popular material for public structures all over the world. The concrete structure is durable enough to keep its shape for a long time.
The reinforced concrete structure refers to the members like beams, boards, columns, and roof trusses etc. which are consisted of concrete and steel bars.
In these structures, the steel bars are covered by concrete but their mechanical properties will still lose due to the fire to destroy the whole structure.
In this design of reinforced concrete structures, the provided reinforced is inserted in the concrete upto a particular distance from the face of the member as there are some reasons.
The reasons are discussed below:
• It will provide protection to reinforcement from erosion
• It will also provide fire resilience to reinforcement.
• It will also supply sufficient embedded depth so that reinforcement grows the requisite stress.
This distance is measured in various ways and known by different names like:
• Clear cover: This is the difference from the face of the member to the outermost face of the reinforcement including shear or torsion Stirrups or links.
• Nominal cover: This cover is like the same as Clear Cover although it has different name; actually the name is a term that is used by the code. It is the distance measured from the face of the member to the outermost face of the reinforcement including Stirrups or links.
