AB - Following casting, concrete cracks if early-age thermal (EAT) and long-term (LT) shrinkagemovement is restrained. Crack control is of particular importance in walls which rely solely onconcrete for water tightness, such as retaining walls and water resisting tanks. It is well establishedthat the cracking behaviour of end restrained members is very different from that of edge restrainedwalls. For this reason, both restraint types are considered separately in literature and in codes ofpractice such as Eurocode 2 (EN 1992). In reality, combined edge and end restraint is present in manyreinforced concrete (RC) structures. In the absence of design recommendations for combinedrestraint, U.K. engineers commonly design crack control reinforcement for end restraint as it is theworst case. In the authors’ opinion, this is wasteful as it leads to the provision of unnecessaryreinforcement. To this end, an experimental programme was conducted to investigate cracking in RCwalls with combined base and end restraint. The measured and calculated crack widths are comparedwith the predictions of EN 1992 for edge and end restraint. The results suggest that crack widths inwalls with combined edge and end restraint can be calculated with the EN 1992 equations for crackingin edge restrained walls.
