000013495 520__ $$2eng$$aA simplified methodology for seismic performance assessment of structures with consideration of both aleatory and epistemic uncertainty is briefly presented. The methodology involves pushover analysis for a set of structural models and nonlinear dynamic analysis of corresponding equivalent SDOF models. However, a methodology by itself without any support of sophisticated computational software is not intended to be used for practical applications. Thus, a very efficient software tool, a PBEE toolbox [1] in conjunction with OpenSees, was used in our study in order to perform pushover analyses of required computational simulations, while nonlinear dynamic analysis are approximately computed by using a web application for prediction of IDA curves [2], which was recently developed within ICE4RISK project. Presented methodology and software tools are demonstrated by means of an example of a three-storey reinforced concrete frame building. The results of the presented example have indicated that incorporation of the epistemic uncertainty, in addition to aleatory uncertainty, slightly increases dispersion and can substantially decrease the limit-state intensities. This effect increases with the severity of the limit state. It was also proved that sophisticated software tools are important ingredient of performance-based earthquake engineering and can significantly facilitate transferring knowledge into practice.
