Numerical Study of Progressive Collapse in Intermediate Moment Resisting Reinforced Concrete Frame Due to Column Removal
Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...
متن کاملEffect of Unreinforced Masonry Infill Walls on Seismic Performance of Reinforced Concrete Framed Structures
Unreinforced Masonry infill walls (URM) are commonly used in the Reinforced Concrete (RC) framed structures as interiors and exteriors partition walls. Although they usually are not considered in the structural analysis and design, their influence on the seismic performance of the framed structures is significant. A common practice in the modern and old RC buildings is to remove the URM walls i...
متن کاملAdaptive Finite Elements for Reinforced Concrete Framed Structures
Abstract. This work focuses on the modelling of nonlinear response of reinforced concrete structures by means of the finite element method. A new technique which employs a variable mesh in order to reduce the computational cost of classical approaches is presented. For some piecewise linear constitutive models which are widely employed for the modelling of reinforced concrete, some properties o...
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...
