A lot of research exists in characterizing the epistemic uncertainty associated with demand and capacity of a structure or a structural component. However very few researches exist on characterizing the epistemic uncertainty associated with high level analytical modeling decisions for simulation of a structure. In this research, epistemic uncertainty in structural response of reinforced concrete structural system has been investigated through a nonlinear pushover analysis of a reinforced concrete column. While performing nonlinear analysis of the structural component with a particular analytical model, the analyst is required to make certain high level decisions such as with respect to element type, integration rules and material models, to obtain the response of a structural component subjected to a certain kind of loading. The research highlights the loss of objectivity in response associated with high level modeling decisions by an analyst.
