Steel, fy (main bars) = 415 Mpa Steel, fyt (ties) = 275 Mpa 1. Determine the minimum spacing “a”, (mm)? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer) 2. Determine the nominal shear strength (kN) provided by the concrete? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer) 3. Determine the nominal shear strength if the lateral ties area is spaced at 125 mm on center? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer
