| Abstract |
In this study the progressive collapse resisting capacity of Special Truss Moment Frames (STMF) was investigated. As analysis models, STMF with various span lengths, numbers of story, and lengths of special segments were designed and their performances were compared. It was observed that all the model structures designed per the ASCE 7-10 collapsed as a result of plastic hinge formation at special segments when a column was suddenly removed. A design procedure was developed to prevent progressive collapse based on the energy balance concept. The model structures redesigned using the developed design procedure turned out to satisfy the acceptance criteria of the GSA guidelines. |
