Comparison between Alternative Load Path Method and a Direct Applying Blast Loading Method in Assessment of the Progressive Collapse
Extensive research has been focused on the progressive collapse analysis of buildings and most of them are based on the alternative path method (APM) with sudden removal of one or several columns. However, in this method the damage of adjacent elements of removed columns under blast conditions was ignored and this issue can lead to an incorrect prediction of progressive collapse. Therefore, in ...
متن کاملComparison of the Progressive Collapse Resistance of Seismically Designed Steel Shear Wall Frames And Special Steel Moment Frames
In this study, the progressive collapse potential of seismically designed steel plate shear wall (SPSW) systems is investigated using the alternate path method, and their performances are compared with those of the conventional special moment frame (SMF) systems. Nonlinear static and dynamic analyses are conducted to follow the progressive collapse of the structures, and their ability of absorb...
متن کاملParametric study of the progressive collapse of 2D framed structures
In this paper we study the response of 2D framed structures made of reinforced concrete to the sudden removal of columns. For comparative reasons, the 2D frames are considered as part of 3D structures with same overall structural mass and external load potential. In particular, we study two sets of 2D frames, with different height-bay ratio λ of the structural cells. Each set counts 3 frames wi...
متن کاملPROGRESSIVE COLLAPSE ANALYSIS OF RCC STRUCTURES
The study aims to investigate the progressive collapse behaviour of RCC building under extreme loading events such as gas explosion in kitchen, terroristic attack, vehicular collisions and accidental overloads. The behavioural changes have been investigated and node displacements are computed when the building is subjected to sudden collapse of the load beari...
متن کاملThreat-Independent Column Removal and Fire-Induced Progressive Collapse: Numerical Study and Comparison
Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...
