PSAD Refresher 80: Shear and Axial Strength of Spiral Column | Reinforced Concrete Design

Check out our Review Center: https://www.facebook.com/share/1AC24W... SITUATION: A 450-mm diameter spirally reinforced concrete column is to be reinforced with 8-20 mm diameter vertical bars and 10 mm diameter spiral. Use fc’ = 28 MPa and fy = 415 MPa. Use the simplified calculation for shear. 1. Which of the following gives the maximum nominal axial strength (kN) of the column? A. 3815 C. 3355 B. 4053 D. 4215 2. Determine the shear strength (kN) provided by the concrete if the factored axial load is 2250 kN. A. 220 C. 125 B. 245 D. 146 3. Determine the shear strength (kN) provided by the reinforcement if the pitch of the spiral is 50 mm. A. 235 C. 345 B. 469 D. 288 Thanks for watching!
