Abstract

The importance of understanding the behaviour of concrete in tension is noted and the major role of tensile properties in the fracture of concrete is examined. Some applications of a tensile strain criterion are discussed together with major influential factors. It is shown that the tensile strain capacity under direct tension can be predicted from the tensile strength and the static modulus of elasticity and that the relation is virtually independent of mix composition, age, specimen size and testing technique, provided that unnotched specimens are used. Prediction is not so good with notched specimens and it is concluded that the former are more reliable for design purposes.
