In traditional structural design, linear elastic behavior is typically assumed for the global structural response as well as for the soil-structure interaction. Although this assumption simplifies the design process greatly, in particular with regard to the multitude of load situations that are to be investigated, it is associated with a high degree of uncertainty. While errors resulting from simple superposition of load cases are of little significance for some structures, this is not true for statically indeterminate frame structures subjected to time variant constraint loads resulting from creep, shrinkage, temperature processes and earth pressure. Within this paper, linearity assumptions that are typically made in the design of frame bridges and ultimately govern performance will be presented and discussed on the basis of available monitoring information for an existing bridge. In particular, the uncertain soil-structure interaction and the structural detail for the transition area between concrete deck and soil are investigated.
