Which of the following relation is correct for I- section of width b and depth d subjected to axial force N together with moment M?

(N/Np) – (1/1.18)(M/Mp) ≤ 1, when N/Np > 0.15

(N/Np) – (1/1.18)(M/Mp) ≤ 1, when N/Np < 0.15

(N/Np) + (1/1.18)(M/Mp) ≤ 1, when N/Np < 0.15

(N/Np) + (1/1.18)(M/Mp) ≤ 1, when N/Np > 0.15
