When converting simply supported single span bridge structures to continuous structures, elastic support conditions in the horizontal direction are provided to absorb the energy of earthquake loading and to distribute the horizontal reaction due to temperature change. However, a possibility of additional stress increase in the transverse cross section of the slab due to the vertical elastic bearings seems to be overlooked in the design process. A verification test with simple beam bridge specimen indicates a significant increase of strain in the transverse direction under the elastic support conditions and a counter-measurement for this increase needs to be provided in the design.
