In this paper, a method concerning analysis of reinforced concrete structures in the serviceability limit state (SLS) is discussed. The method is based on elastic energy principles, combined with simple assumptions with respect to concrete mechanics. This approach allows for a direct implementation of the choices, made in relation to the design of the structure with respect to the ultimate limit state (ULS). Hence, a rational link between the two states is established. The approach is appropriate for the design of new structures and assessment of existing structures. The method and the link between the choices made regarding the ULS and the state of stress in the SLS is compared with tests on reinforced concrete disks and beams, respectively. Fairly good agreement between theory and tests is achieved.
