Flexural design support C

At centreline of support M = 516.0 kNm

K = MEd / bwd2fCk where bw = 2000 mm d = 226 mm as before

K = 426.0 x 106/(2000 x 2262 x 35) = 0.119 By inspection, K < K' z = (226 / 2) [1 + (1 - 3.53 K)05] = (226 / 2) [1 + (1 - 3.53 x 0.119)05] = (226 / 2) (1 + 0.76) < 0.95d = 199 mm
