Progressive Collapse Mechanisms of Brittle and Ductile Framed Structures
In this paper, we study the progressive collapse of three-dimensional framed structures made of reinforced concrete after the sudden loss of a column. The structures are represented by elastoplastic Euler-Bernoulli beams with elongation-rotation failure threshold. We performed simulations using the discrete element method considering inelastic collisions between the structural elements. The res...
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 کامل1 DEM Simulations of the Progressive Collapse of Framed Structures
Progressive collapse of framed structures is a complex topic going beyond the usual tools of structural mechanics. The analogy with the propagation of damage in the framework of fracture mechanics has already brought some theoretical results, especially when the energy fluxes are analyzed. Nevertheless, the difficulty to get representative experimental data avoids proposing and eventually provi...
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 کاملNumerical Study of Progressive Collapse in Framed Structures: A New Approach for Dynamic Column Removal (TECHNICAL NOTE)
Progressive collapse is a situation where local failure of a primary structural component leads to the collapse of adjoining members which, in turn, leads to additional collapse. Hence, the total damage is disproportionate to the original cause. The most common local failure in framed structure is assumed to be column failure. In this paper, a new approach for dynamic column removal in framed s...
