Summary:In this study the progressive collapse resisting capacity of the Special Truss Moment Frames (STMF) was investigated. To this end STMF with various span lengths, numbers of story, and lengths of special segment were designed. Their performances against progressive collapse were evaluated based on arbitrary column removal scenario. It was observed that all the model structures designed per the AISC Seismic Provision collapsed as a result of plastic hinge formation at special segment when a column was suddenly removed. A design procedure was developed based on the energy balance concept to prevent progressive collapse. The model structures redesigned using the developed design procedure turned out to remain stable after a column was suddenly removed and satisfy the acceptance criteria of the GSA guidelines.
