THE STRUT-AND-TIE MODEL
For an undisturbed and uniaxial state of compressive stress: f cu = 1.0 (0.85 f c?) = 0.85 f c? If tensile strains in the cross direction or transverse tensile reinforcement may cause cracking parallel to the strut with normal crack width: f cu = 0.8 (0.85 f c?) = 0.68 f c? As above for skew cracking or skew reinforcement: f cu = 0.6 (0.85 f c ...
