When existing simple span bridges are converted into continuous spans, rigid support conditions have to be changed to elastic supports in order to absorb and distribute the energy of horizontal motion due to an earthquake loading. However, development of additional reaction forces and stresses on the slab due to unequal displacement of the elastic supports have been overlooked. In this study, two-span continuous specimen, which is converted from two simple span structures through the “No-Joint” method, is tested and analyzed to investigate the stress distributions of the concrete slab. Durability of the concrete slab under the elastic supports is also discussed.
