Behaviour of concrete under various loads Concrete very rarely undergoes a crushing or compression failure Typically tensile strains generated in the lateral direction (perpendicular to the loading direction) due to Poisson effect are responsible for cracking leading to failure of concrete Let us consider various cases of loading concrete (in all the cases the effects of friction at the ends is neglected) as shown in
