Problem#01: For the given beam section below find the design moment \( (\Phi M n) \) and \( C \) whereas \( f^{\prime} c=5 \mathrm{ksi}, \mathrm{F}_{\mathrm{y}}=50 \mathrm{ksi} \), check if the section is tension controlled. a) Using design tables b) Using ACl specification
Expert Answer
Explanation: Given: f'c = 5 ksi = 5000 psi fy = 50 ksi = 50,000 psi b = 10 in d' = 2.5 in h = 24 in d = 24 in - 2.5 in = 21.5 in As = 4-#8 = 4?(1in)²/4 = ? in² ? = 0.85 - (f'c-4000)(0.05)/1000
