Non-linear Incremental Dynamic Analysis (IDA) is used for the analysis the structure and to generate fragility curves for this type of bridge. Finite element models are constructed for three types of integral abutment bridges. Simulation are performed considering and neglecting the SSI effects. A total of 20 selected ground motions was used in the IDA of the bridge models. The spectral acceleration of ground motions is chosen as the Intensity Measure (IM) and relative displacement and drift of the abutment back walls and pier columns are chosen as engineering demand parameters (EDPs). The Collapse Margin Ratio (CMR) is chosen as a measure to objectively compare the response of non-SSI and SSI models. In the cases studied here, the SSI models showed significant reduction in collapse margin ratio when compared to their counterpart non-SSI model. This indicates that ignoring the soil effect may result in under estimation of the probability of collapse.
