Crack width in Tunnels: A thesis on the accuracy of the Eurocode 2 crack width calculation of flexural cracks in structures with large thicknesses.

When engineers at Tunnel Engineering Consultants (TEC) used the Eurocode 2 (EC2) for the verification of flexural cracks in cross sections of immersed tunnel elements, they found out that there was more reinforcement needed for crack width limitation than for tensile strength of the reinforced concrete. This raised questions, namely whether the...
