A 300mm thick retaining wall is cast against a stiff raft foundation. The wall is 15m long with no movement joints. Calculate the crack width due to early-age thermal contraction.
The worked example walks through the exact method formula for $s_r,max$ (maximum crack spacing), accounting for bond properties: $$s_r,max = k_3 c + k_1 k_2 k_4 \frac\phi\rho_p,eff$$ It then recalculates $w_k$, proving that while simplified tables are conservative, the exact method saves unnecessary reinforcement up to 15%. worked examples to eurocode 2 volume 2
