Incremental dynamic analysis has been extended by introducing a set of structural models in addition to the set of ground motion records which is employed in IDA analysis in order to capture record-to-record variability. The set of structural models reflects epistemic uncertainties, and is determined by utilizing the latin hypercube sampling (LHS) method. The effects of both aleatory and epistemic uncertainty on seismic response parameters are therefore considered in extended IDA analysis. It is shown that epistemic uncertainty could have a significant influence on collapse capacity.

New European standards for the design of structures for earthquake resistance have introduced several novelties in the design practice, including non-linear seismic response analysis methods. For wider implementation of nonlinear methods in design practice specialized software tools that enable a user-friendly non-linear model definition and transparent representation of analysis results is needed. Such software tool for seismic assessment of simple RC bridges according to Eurocode 8 is presented in the paper.
