Happy Wednesday everyone, Most reinforced concrete elements crack. And that’s OK. This doesn’t mean that the elements fail. It just means that the tensile capacity of concrete is exceeded and that the concrete fails. From that moment, the reinforcement takes up all the tensile forces/stresses that act in the element due to a bending moment or a shear force. As I said, cracking is OK, and we structural engineer design elements for it. But cracking is only OK to a certain extent. The cracks...
