Recent studies regarding progressive collapse resistance of buildings considered only single critical column removal scenario. However, limited investigations have been conducted so far to assess multi-column removal scenarios. Hence this study is made to compare progressive collapse resistance of a multi-story building under both single and multi-column removal scenarios. An eight-storey reinforced concrete building was analyzed by using linear static analysis procedure and DCR values of the members are calculated to investigate the potential of progressive collapse as per GSA guideline. The values of DCR are compared for different cases. Comparisons of single and multi-column removal scenarios reveal that later scenarios are more critical because of their higher demand capacity ratios, and it is more critical when both corner and exterior columns are removed.

Progressive Collapse Analysis

This project presents an attempt to do static, dynamic and progressive collapse analysis of multistory (G+10) residential building by ETABS (Extended 3D Analysis of Building Systems). ETABS is software that helps to anatomization and design of low and high-rise buildings and frame structures. In this project G+10 RC frame building is analysis statically (linear method) and dynamically (Response Spectrum method) along with Progressive Collapse analysis. All the members of the project are analyzed as per Indian codes IS 456:2000, IS 800:2007, and IS 1893:2002 (part1) code using this software. Here the result for Story stiffness, Base shear, Story Shear, Overturning moments, Maximum displacement, and Story Drift is compared between static and dynamic results for Zone2-(case1), Zone3-(case2), Zone4-(case3), Zone5-(case4) with medium soil type and for Progressive Collapse analysis GSA guidelines are followed. As per GSA guidelines three column removal cases for each case1, case2, case3, and case4 individually studied, namely Corner column removal, Exterior column removal and interior column removal at ground floor. For all three cases linear analysis study has been undertaken and DCR ratios are evaluated. Member having DCR ratio greater than 2 will going to fail for corresponding column removal case.

Progressive Collapse Analysis

This project presents an attempt to do progressive collapse analysis of multistory (G+10) residential building by STAAD Pro (Structural Analysis and Design Software Application). STAAD Pro is software that helps to analysis and design of low and high-rise buildings and portal frame structures. In this project G+10 RC frame building is analysis statically (linear method) along with Progressive Collapse analysis. In progressive collapse the weight of the building transfers to the neighbour columns in the structure causes to the failure of adjoining members and finally to the failure of partial or whole structure. All the members of the project are analyzed as per Indian codes IS 456:2000, IS 800:2007, and IS 1893:2002 (part1) code using this software. Here the result for is compared between the shear force, bending moment variations value of corner column, Zone1, Zone2, Zone 3 by STAAD Pro. With medium soil type and for Progressive Collapse analysis GSA guidelines are followed. As per GSA guidelines three column removal cases for each case1, case2, case3 one at a time has studied, namely Corner column removal, Exterior column removal and interior column removal all at ground floor.

Progressive Collapse Analysis

With no beams, reinforced concrete flat slab buildings are typically built to advance urban growth and to meet the architectural needs of large spans and low storey heights. Its behaviour to avoid a progressive collapse must therefore be investigated. In this research, the progressive collapse resistance of six-storey RC flat slab buildings with varying span lengths and floor heights is assessed by subjecting the building to three different instances of instantaneous removal of columns in the first storey, performing dynamic progressive collapse analysis as per GSA guidelines, and comparing the evaluated joint displacements and chord rotations at column removal locations with the permissible chord rotation for flat slab buildings as per DoD guidelines. The results have shown that the studied flat slab building with all different span lengths and floor heights is prone to progressive collapse. It is also observed that the vertical displacements and chord rotations at column removal positions increase as the span lengths and storey heights are increased alternately.

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.
