Numerical Modelling of the Progressive Collapse of Framed Structures as a Result of Impact or Explosion
نویسندگان
چکیده
A definition of progressive collapse is offered and two examples of the phenomenon described. Attention is drawn to potential sources of abnormal loads that should be examined when designing for progressive collapse performance. A plane frame computer program is described for the collapse analysis of reinforced concrete frames using finite elements and a quasi-static approach. The paper concludes by discussing the on-going development of a 3-dimensional dynamic/quasi-static non-linear finite element computer program for more accurate analysis.

Numerical 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...
متن کاملProbability Assessment and Risk Management of Progressive Collapse in Strategic Buildings Facing Blast Loads
Nowadays, as a result of increased terrorist and bomb attacks throughout the globe in the vicinity of strategic buildings, designing these structures against impact loads, particularly the blast-related ones, has been taken into more consideration. The current procedure for designing the structure against an explosion is a design against the local failure of the current elements in the first st...
متن کاملNumerical Evaluation of Progressive Collapse Potential in Reinforced Concrete Buildings with Various Floor Plans Due to Single Column Removal
Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

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 کاملInvestigation 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...
