Concrete: P M Interaction curve
#3
Dear kowheng
firstly; you can say that N(kn)=P(kn)
Secondly
i entered below expression
N=0.85Fcdab+As/2(So+Su)+AmSm
M=0.85Fcdab(h-a)/2+As/4(So_Su)(d-d')

Reinforced concrete c30 (fcd=20Mpa ,k1=0.82)
steel s420 (fyd=365 Mpa)

you can see above that tension's unit Mpa
in order that convert the expressions,i multiplied 10^3

i hope ,i explained that
regrds
urbana
