Several prototype steel moment-frame buildings have been designed for the purpose of assessing their reserve capacity and vulnerability to progressive collapse. Designs were developed for both seismic and non-seismic regions. This paper summarizes the development of three-dimensional finite element models of these prototype buildings, with a focus on the modeling approach used for the connections and the composite floor system. Initial simulation results under a column removal scenario are presented to illustrate the model capabilities. Vulnerability assessments using these models are part of a larger study aimed at quantifying and comparing the relative robustness of different structural systems.
