Progressive Collapse Analysis

The developments in construction make it compulsory for architects to plan the high rise structures in RCC. Unfortunately due to some reasons like gas explosion, terrorist attack, fire etc. high rise structures undergoes some major component failure. As the major component fails, sometimes part of the structure or whole structure tends to collapse. This behavior of the structure is called as progressive collapse. Progressive collapse may be a chain reaction of failures that circulates either throughout or some of the structure lopsided to the first local failure. The progressive collapse of building structure is commenced when one or more vertical load carrying members are removed. One of the important characteristics of progressive collapse is that the final damage is not related to the initial damage. In this project it is proposed to carry out progressive collapse analysis of regular and irregular structures. Structural model of building has been fashioned din ETABS and loads are applied as per GSA guidelines, for evaluation of progressive collapse nonlinear static method of analysis has been used. The analysis is done using ETABS 18 software and using codes of analysis, IS 1893: 2016, IS 456: 2016. Joint displacements, axial force, bending moment are evaluated. In all cases progressive collapse of internal column is more critical as compared to other cases.

Progressive Collapse Analysis

The Oseberg jacket was installed at the Oseberg field in the North Sea during the summer of 1987 and the production started on December 1, 1988. On March 6, 1988, a submarine accidentally impacted with the Oseberg jacket. This paper presents results from the evaluation of the importance of the damage to the overall structural safety. A nonlinear progressive collapse analysis is applied for the safety check. The theoretical computations are verified through evaluation of strain and acceleration time series recorded during the submarine impact. The reduction in the overall structural capacity of the jacket was in the order of 10 percent. However, the local member capacity was significantly reduced and it was necessary to remove the damaged member in order to obtain the initial level of safety.
