“…For this project, the Applied Element Method (AEM) [29] was selected, due to its ability to reliably model progressive collapse and the large displacements associated with debris distribution [30,31]. AEM is a discretised model in which the internal forces are modelled by shear and normal springs which connect neighbouring elements along the faces.…”

“…Thus, APM method is preferred over all the other methods for its simplicity and adoptability for both static and dynamic analysis procedure for reinforced concrete structures subjected to seismic actions. Based on the GSA guidelines [4], [5], [6], [7] To determine the potential of progressive collapse for a structure, following four different column removal cases are considered to determine the response of the structure and to know key effects of different parameters on deformation arising due to column loss: 1) A column located at the corner of the building in first floor 2) An exterior column near middle of long side of the building in first floor 3) A column interior to perimeter, intersecting column lines…”

Progressive collapse is a catastrophic structural event that occurs when failure of one or more structural member in the structure initiates a chain reaction resulting in partial or total collapse of the structure.To study the behavior of RC structure under the influence of seismic actions a load bearing vertical element like wall or column is removed and evaluated using nonlinear static pushdown analysis. For this a 3-D model is stimulated and a nonlinear static analysis is performed by removing a critical column at desired location in the plan prescribed by General Service Administration (GSA) guidelines. The importance of beams during a column loss is evaluated in the present study to resist possible progressive collapse.

“…The FEM based analysis of PC of RC structures suffering column loss is discussed in [46]. Problems of progressive collapse of reinforced concrete structures exposed to earthquakes are discussed in [47,48]. Paper [2] explains the phenomena of progressive collapse and proposes the above mentioned term disproportionate collapse for such collapse.…”

The robustness of a reinforced concrete (RC) five-storey building (frame system stiffened by walls) is analysed in the paper. A high ductility class structure is designed in accordance with structural Eurocodes. The response of the structure to eight different scenarios of the ground floor vertical element loss is analysed. Nonlinear Static Analysis (NSA) and Nonlinear Dynamic Analysis (NDA) methods are used for the robustness analysis. Fragility curves of the building are derived from statistical analysis of these results. The values obtained through NSA and NDA, damage limit states of the system, and fragility curves, are compared. The influence of the position of the removed element on robustness of the structure is also analysed.
