10A. DIMENSIONING PART 1/4

• (EC2) modify, if necessary, the constants K* *EC2§7.3.4 K1 : is a coefficient to take into account the congruence properties of the reinforcement with congruence: K1=0,8 for high affinity bars K1=1,6 for bars with a practically smooth surface K2 : is a coefficient to take account of the distribution of deformations K2=0,5 for bending K2=1,0 for net tensile strength K3=3,4 K4=0,425 The control of "Bending Needles" in the beams according to EC2 is done by selecting the corresponding control in the beam sizing parameters. This is where the upper limit (l/a) of the deformations is determined. The results of the check are displayed at the end of the investigation file
