The current paper investigates the problem of structural progressive collapse.A two-bay small scale reinforced concrete frame has been casted without the intermediate column and dynamically-loaded until failure in order to investigate its behavior and strength under column loss condition. During the test, deflection, cracking, longitudinal strains in both steel bars and concrete, ultimate loads and mode of failure have been monitored. Additionally, an F.E model, using Abaqus 6.13 program is presented.In the numerical model, strain rate effects have been considered. The tested frame was prepared and casted in the reinforced concrete laboratory, faculty of Engineering, Menoufia University while the testing process took place in reinforced concrete laboratory, faculty of Engineering, Tanta University.

“…This is the main reason why the column removal approach has formed the basis of many research studies conducted during the past few years. Those studies have involved experimental testing, detailed finite element simulation and analytical modelling of the behaviour of isolated key components such as beam-column connections [6][7][8][9][10][11] or substructures at various levels of idealisation such as beam-column assemblies [12][13][14][15][16][17][18][19] (though some have mainly focused on connection behaviour [16][17][18] ), complete 2-dimensional plane frames [20][21][22][23][24][25] and 3-dimensional grillage/floor arrangements [26][27][28][29][30][31][32] . Some new developments feature in the most recent Guidelines to progressive collapse 33,34 .…”

The topic of progressive collapse of structures has increasingly received particular consideration over recent years, with numerous studies of various forms having been seeking to explore the complex mechanics of the problem and define ways of minimising its effects. Through a continuing research program at Imperial College London, considerable advance has been made in understanding the physical features of the progressive collapse response of frame structures, identifying the role of the several different controlling parameters and compiling simplified methods for simulating particular effects. Knowledge of the subject has, therefore, been improved to a considerable extent, that is now possible to make quantitatively justified assessments of structural robustness by specifying the reasons why a structure might be susceptible to progressive collapse as well as to identify potential methods for enhancing performance. The present paper reviews previous developments at Imperial, evaluates information obtained from relevant experimental studies conducted by other research groups and makes an assessment of the progress made both in developing a scientific understanding of the subject and establishing improved ways of tackling the problem in practice.Several factors that should be considered in the robustness design of steel and composite frame structures are defined as well as needs for further research into specific aspects of the problem are identified.

“…Yang and Tan [1][2][3][4][5] conducted a series of quasi-static tests and numerical analyses of both bare steel frames and composite frames. Based on these tests, a component-based model was proposed to predict the response of bolted-angle connections [6], and this model was further developed to simulate the behaviour of composite beam-column joints under middle-column-removal scenarios [7]. Progressive collapse is a dynamic process.…”

During the past decade, many quasi-static tests were conducted on structures against progressive collapse. As a typical testing method, middle-column-removal scenario was used in most studies. It should be noted that another important scenario, i.e. falling floor impact, may also cause progressive collapse. In this paper, a series of numerical analyses was carried out to study the dynamic behaviour of steel beams subjected to falling floor impact. Fin plate connections were used to connect the beam and the columns. 3-D finite element models (FEM) were established by ANSYS/LS-DYNA and validated against experimental data. Good consistency was shown between experimental tests and numerical analyses. By using the validated finite element models, four parameters including strength of material, impact load, impact location and inertia effect were studied. High strength materials were beneficial to enhance the impact resistance in the falling floor impact scenario. Higher impact velocity can slightly improve the capacity of energy dissipation. For location of falling impact, it was more critical if the hammer dropped onto the joint region compared to the mid-span region. The inertial effect should be considered in the impact analyses because it significantly decreased the maximum vertical displacement of specimens.
