In this study a numerical simulation of the behaviour and failure modes of axially compressed steel column subjected to transverse impact by a rigid mass at different impact speeds and locations is presented. Firstly, the capability of the present numerical model to trace the response and to predict different failure modes of transversely impacted beams and columns with and without axial compressive force has been validated. These failure modes include plastic global failure, tensile tearing failure and transverse shear failure. The validation was performed by comparing simulation results in term of the contact force, deformation shape, failure mode and the maximum transverse displacement with available published experimental test results by others. The progressive damage and failure model available in ABAQUS/Explicit has been utilized in the present numerical models to account for material shear and tensile tearing failure under impact. Comparisons between the experimental and simulation results confirmed that the numerical models were able to accurately predict the aforementioned failure modes. Thereafter, a parametric study has been conducted to investigate the effects of several parameters on the response of axially loaded steel column, based on the results of which simplifying assumptions on column behaviour under impact can be made to develop appropriate design calculation methods for steel columns under such loading conditions.

“…The post-impact damage of all specimens exhibited brittle shear-type damage, which is characterised by one main diagonal crack starting from the impact point to the bottom of RC columns. Adachi et al [10] conducted an experimental investigation on the buckling behavior of a column subjected to a transverse impact during static axial compression in relation to structural energy absorption. It was found that the critical condition of buckling generation was determined by the kinetic energy of the impactor, irrelevant to the impact force history.…”

By using the ABAQUS finite element (FE) model, which has been verified by experiments, the deformation and internal force changes of RC columns during the impact process are investigated, and a parametric analysis is conducted under different impact kinetic energies Ek. According to the development path of the bottom bending moment-column top displacement curve under impact, the member is in a slight damage state when the curve rebounds before reaching the peak and in a moderate or severe damage state when the curve exceeds the peak, in which case the specific damage state of the member needs to be determined by examining whether there is a secondary descending stage in the curve. Accordingly, a qualitative method for evaluating the bending failure of RC column members under impact is obtained. In addition, the damage state of RC columns under impact can also be quantitatively evaluated by the ratio of the equivalent static load Feq and the ultimate static load-bearing capacity Fsu.

“…So far, the dynamic response of lattice shell structure has been mostly examined under seismic load [3][4][5][6][7][8][9], but rarely under impact load. The few studies that consider impact load mainly focus on plane frames, road protection facilities, and single beam-column members [10][11][12][13][14][15].…”

The lattice shell structure is widely adopted in large-span spatial structures (LSSSs). Under impact load, the steel column supports have a great impact on the working performance of the lattice shell structure. To ensure the impact resistance of the structure, this paper establishes a finite-element model of a single-layer latticed shell with steel column supports, and applies the model to analyze the nonlinear dynamic response of the latticed shell structure under the lateral impact from a heavy vehicle. In addition, the authors examined the influence of three factors, namely, peak impact load, lateral stiffness of support and number of impact points, over the latticed shell structure under the said impact. The results show that: except for the impacted support and rods connected to the support, the entire latticed shell structure is basically in an elastic state. Overall, the working performance of the latticed shell structure is not damaged by the impact load, that is, the structure still enjoys satisfactory strength and stability, with no dynamic instability. Hence, the latticed shell structure boats good working performance under impact load.
