As in the seismic design, to resist such catastrophic loads, structuresshould be provided with an adequate level of structural continuity, redundancy,robustness and ductility, so that alternative load transfer paths can develop when thestructure loses an individual member. Following the GSA Guidelines (2003), the paperpresents an investigation regarding the vulnerability to progressive collapse of a modelrepresenting a 13-storey RC framed building when its seismic design was madeaccording to the provisions of the present seismic code P100-1/2006. . Numerical resultsregarding the behavior of the model when the structure is damaged by the suddenremoval of a corner column are given. Demands and capacities of structural members areassessed and DCR values for the lower part of the building are presented. A typicalmedium–rise building having RC frames seismically designed for Bucharest according toseismic design code P100-1/2006, does not experience failures or progressive collapsewhen subjected to different “missing column” scenarios, including the removal of acorner column.
