Concrete is much stronger in compression than in tension (tensile strength is of the order of one-tenth of compressive strength). While its tensile stress-strain relationship is almost linear [Fig. 1.1(i)], the stress ( ) vs. strain ( ) relationship in compression is nonlinear. Fig. 1.1(ii) shows a typical set of such curves.
