Abstract
In this study the progressive collapse resisting capacity of the special truss moment frames (STMF) was investigated. As analysis models, STMF with various span lengths, numbers of storeys, and lengths of special segment were designed and their performance compared. It was observed that all the model structures designed as per the ATSC seismic provision collapsed as a result of plastic hinge formation at the special segment 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 remain stable after a column was suddenly removed and satisfies the acceptance criteria of the GSA guidelines.
