Concrete in tension area
There are several options available for the stress-strain diagram of the concrete in the tension area.
The concrete tensile strength can, inter alia, be considered according to CEB-FIP Model Code 90:1993. Until the tensile strength of concrete fctm is reached, the program assumes the distribution shown in Figure 2.134 for reaching the crack strain of 0.15 ‰.
Alternatively, you can use the concrete's stiffening effect in the tension zone (tension stiffening). This procedure is described in the following chapter.
