The concrete filled with steel which named reinforced concrete steel reinforced concrete structure (SRC), and it gives full play to the characteristics of two kinds of steel and concrete materials.
Among the simulation, the relative slip between materials is not used, and the "binding" is considered in the interaction between each interface, which it only has the force send on the contact surface and has no relative displacement.

During the diffusion process materials CFT KIc=KIc(Ca) decreases being a function of Ca and, when certain critical average concentration Ca* is reached, CFT reaches the value of the current stress intensity factor KIσ∞,l=KIc(Ca*) and crack length increases by the prerupture area length ad.
The efficiency areas of the materials CFT are showed with respecting qCRcl.
