Investigation of the Progressive Collapse Potential in Steel Buildings with Composite Floor System
Abnormal loads due to natural events, implementation errors and some other issues can lead to occurrence of progressive collapse in structures. Most of the past researches consist of 2- Dimensional (2D) models of steel frames without consideration of the floor system effects, which reduces the accuracy of the modeling. While employing a 3-Dimensional (3D) model and modeling the concrete slab sy...
متن کاملEffect of Initial Local Failure Type on Steel Braced Frame Buildings against Progressive Collapse
In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...
متن کاملA Parametric Study on the Progressive Collapse Potential of Steel Buildings under Truck Collision
In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...
متن کاملAnalysis Procedures For Progressive Collapse of Buildings
This paper presents simple analytical approaches for evaluating progressive collapse potential of lowand mid-rise buildings that could be used in routine design by design professionals. Although nonlinear time history analysis would be more realistic in representing progressive collapse phenomenon, high fidelity structural models to represent nonlinear structural behavior are required to produc...
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...
