Reinforcement Steel Material
Minimum characteristic yield strength of reinforcement steel has 420 MPa, a tensile strength between 1.15 and 1.35 times the characteristic yield strength and B420C steel with a strain corresponding to the tensile strength of 8%.
The design strength fyd is obtained by taking the reinforcement steel material safety coefficient 1.15 .
