Dear All Safiance,

Any body please elaborate the concrete crack analysis and identification.

How to judge the crack whether it is structural or non structural in members.

Generally cracks in concrete in compression zone can be considered as structural.Because it will damage structural strength of concrete such as cracks due to shear flexure etc. Other cracks which occur in the tensile zone of concrete can be considered as non structural.Because its effect is of minor influence on member.

Dear Mr. Raju


From where you got this idea? Structural and non-structural cracks are defined with respect to whether they will affect the performance of the structure and definitely not defined with reference to compression zone or tension zone. Concrete is weak in tension and hence reinforcement is provided to resist tension. Crack in the tension zone is dangerous as it will give rise to ingress of water and other chemicals to the reinforcement,  which will result in corrosion leading to failure of the structure.

Best wishes
