Progressive collapse analysis of composite steel frames subject to fire following earthquake

Abstract

This paper presents three-dimensional progressive collapse analyses of composite steel frames exposed to fire following earthquake. The scenarios of heating columns located in various different fire compartments (internal, edge and corner bay) are first studied to investigate load redistribution paths and members' interactions within the composite frame. The results show that the loads previously supported by the heated columns are redistributed to adjacent columns along two horizontal directions, a phenomenon which cannot be captured in a 2D model. Then, the 3D model is adopted to investigate the effect of residual deformation after an earthquake on the progressive collapse behaviour of the composite building. It is found that neither the load redistribution path nor the fire resistance of the building is considerably affected by the residual deformation. A series of progressive collapse analyses subjected to travelling fires resulting from fire compartment damage is also performed. It is concluded that the survival of the building can be greatly affected by the spatial nature of the travelling fire as well as the inter-zone time delay.

Performance of steel moment-resisting frames in post-earthquake horizontally traveling fire

“…This study adopted an in-plane finite element model of the case study frame for its simplicity and computational time; however, it is essential to note such a model ignores the out-of-plane redistribution of forces observed in experimental and 3-D numerical investigations (Suwondo et al, 2019). Also, the reinforced cement concrete (RCC) slab's beneficial effects due to the composite action between steel and concrete and the tension field action of the RCC slab cannot be realized in a two-dimensional model.…”

“…However, global stability was not compromised in either fire scenario (Behnam and Rezvani, 2016). In another study, Suwondo et al (2019) considered a three-dimensional finite element model of a composite steel building for conducting a series of progressive collapse analyses in the FO and PEF scenarios. The residual deformation in the frame and the fire compartment's damage, which may alter the building's fire propagation, was studied.…”

Analysis of the robustness of a steel frame structure with composite floors subject to multiple fire scenarios

“…More recent studies have developed 3D frame models to study the robustness of steel frames with composite slabs in fire situations (Agarwal & Varma, 2014; Jiang and Li, 2017a, 2017b; Suwondo et al, 2019). The results showed that 3D models predict different collapse modes and load redistribution paths compared to those of 2D frames.…”
