Cracking for Low-reinforced RC Members under Uniaxial Tension

Given the random nature of crack formation, research into reinforced concrete members in the context
of cracking behavior proves difficult. Therefore, widely accepted methodologies for predicting crack
characteristics, e.g. crack width and spacing and number of cracks, have not been developed yet.
Furthermore, cracking for members strained until high degrees of elongation, as takes place during
earthquakes, has not been investigated before. This experimental work aims to look into the impact,
primarily of tensile deformation’s mechanical factor, in terms of cracking behaviour. Four test
specimens were strained under uniaxial tensile loading. The degrees of elongation used were equal to
10‰, 20‰, 30‰ and 50‰. Useful conclusions concerning cracking behaviour are derived.
