“…This paper expands on previous work done by the authors in the field of structural robustness and applies a Partial Distributed Damage Method (Gerasimidis andSideri 2016, Sideri et al 2017) in 3D multi-story steel framed and concrete composite buildings. This method assumes that damage is being distributed in more than one components, as a common output of real-case extreme events.…”

“…The response of the research community to the phenomenon has focused around three main themes: computational (Main et al 2014, Kwasniewski 2010, Li et al 2014, Bao et al 2016, Pantidis and Gerasimidis 2017b, Pantidis et al 2018b), experimental (Johnson et al 2016, Dinu et al 2016, Gouverneur et al 2013, Weigand and Berman 2013 and theoretical (Izzudin et al 2008, Pantidis and Gerasimidis 2016, Pantidis and Gerasimidis 2017a, Pantidis and Gerasimidis 2018a,, Gerasimidis 2014. Theoretical approaches to the investigation of the progressive collapse phenomenon have been appearing in the literature with a lower frequency due to the inherent complexity of the problem at hand and the difficulty to describe the nonlinear phenomena associated with it.…”

“…The yielding type collapse mode has been thoroughly studied in the literature. On the other hand, in recent years there have been many papers which have identified a stabilityrelated collapse mode for progressive collapse events (Pantidis et al 2017, Pantidis et al 2018, Gerasimidis et al 2015and Gerasimidis et al 2014. This stability induced collapse mode can appear either through the short-wave instability failure of a column between floors or through a longer-wave mode of a part or even the whole structure (Bazant 1972, Bazant 1973.…”

The prevailing analysis approach in the field of disproportionate collapse of structures is the alternate path method (APM). This method adopts the notion of a complete removal of a key load-bearing component of the system, such as a column or a shear wall, and investigates the capability of the remaining structure to bridge over the loss of this component. Though it offers a practical and efficient tool for the assessment of structural robustness, the complete column loss scenario is a rather unrealistic idealization of damage initiation. This study expands on previous work done by the authors in the field of structural robustness and applies a partial distributed damage method (PDDM) in 3D multi-story steel framed and concrete composite buildings. This method assumes that damage is being distributed in more than one components, as a common output of real-case extreme events. Using advanced nonlinear finite element modeling, this work applies a PDDM scenario in a prototype structural system and evaluates its mechanical performance, making direct comparisons with the APM with regards to the governing collapse mechanism, structural capacity, and damage progression path.Structures Congress 2020 Downloaded from ascelibrary.org by 44.224.250.200 on 07/16/20.

to describe the concept of the progressiveness of damage and the quantification of the property of structural systems to resist progressive collapse. Another pioneering paper presenting many aspects of progressive or disproportionate collapse analysis is [4], which highlights the distinction between direct and indirect methods of analysis and introduces tools associated with the measurement of risk arising from abnormal hazards that can trigger progressive collapse.Numerous researchers have studied the problem of steel buildings under extreme conditions through a multitude of different approaches ([5] to [15]). The work in [16] and, in particular [17] emphasized at a conceptual level the critical importance of investigating the global stability of the structure when performing progressive collapse analyses as well as the need to examine the global response of a damaged structural system.The present paper utilizes the findings included in [17] and [18], comprehensively examines the instability of 2D steel frames when exposed to progressive collapse and investigates the effect of different strengthening schemes on the progressive collapse capacity of a structure.2 Progressive collapse analysis of moment-resisting steel frames 2.1 Description of frames, FEM models and applied loadsThe moment-resisting steel frames are modelled in 2D and shown in Fig. 1: four 4-bay frames with 15, 12, 9 and 6 floors. The storey height is 3 m and the bay width is 5 m, resulting in total heights of 45, 36, 27 and 18 m respec- Progressive collapse mitigation of 2D steel moment framesAssessing the effect of different strengthening schemes Simos Gerasimidis Charalampos BaniotopoulosThe problem of the progressive collapse of structures is today at the forefront of structural engineering because of multiple natural and man-made hazards, the aging of the infrastructure and the catastrophic consequences associated with that. This paper investigates the effects of different strengthening techniques for mitigating the phenomenon of progressive collapse for 2D steel moment frames. These techniques are applied to a series of moment frames of varying heights and designs using a finite element analysis involving both material and geometric non-linearities. The results of this work demonstrate that, when analysed as 2D assemblies, realistic, similar steel frame structures undergo different collapse mechanisms and that a general strengthening scheme cannot be applied to all collapse mechanisms.

Progressive Collapse Modeling of a Steel Structure With Composite Slab Using Commercial Finite Element Software

This paper presents a study on the modelling approaches for column loss scenarios using software that is widely available to structural engineers worldwide, with the goal of providing practical guidance to designers faced with the need or the opportunity to perform progressive collapse analyses. The presented study leverages recent experimental results on column removal in a composite frame obtained at the University of Trento. Comparisons between experimental data, results of high-definition finite element analyses, and the simulation results obtained using commercially available software are performed and conclusions are drawn based on the modelling approach used. Furthermore, a parametric study on various column loss scenarios in a prototype building is conducted and the results are compared with highdefinition model results in literature. It is concluded that the proposed modelling approach can be successfully used in practical cases, with results that are quite satisfactory both at the local and at the global level.
