One steel column is modelled with 4 meter long, HE500B section, S235 steel and 200 GPA Young's Modulus. A relative hinge length of 0.0313 is assigned with PMM interaction according to that Table 9-7.1 in ASCE41-17.

When calculating the interaction diagram for P/Pye=0.2, it implies that 9/8*(1-P/Pye)=9/8*(1-0.2)=0.9. However, SAP2000 shows the value of 0.944 when the P/Pye=0.2.

Is there any reason why SAP2000 finds this value?
