Guidelines for considering manufacturer data and safety factors. 2. Core Calculation Steps (Simplified Example) SF = Mr / Mo = 7,650 / 4,500 = 1

Required reinforcement: ( d = 1500 - 70 = 1430 , mm ) ( K = M/(b d^2 f_ck) = 635e6 / (1000 \times 1430^2 \times 30) = 0.0104 ) → very low → minimum reinforcement governs. 650 / 4
