“…For instance, Zhou et al [8] analyzed ship-bridge collision forces as delineated in differing standards and devised a theoretical formula supported by finite element analysis, considering cumulative damage in their calculations. Song et al [9] performed numerical simulations that resulted in 45 time-history curves of ship-bridge collision forces to assist in parameter identification within collision models and aid in the prediction of impact loads over time. Consolazio [10] proposed the recommended bow extrusion curve and revised the AASHTO formula based on an analysis of multiple high-resolution bow-crushing simulations.…”

The accurate prediction of the collision force magnitude resulting from ship berthing on docks is crucial for the rationality and safety of dock structural design. This paper presents a novel framework for the calculation of berthing collision force for ships (CBCF), which integrates field data, finite element models, and surrogate models. Based on field data and finite element analysis, the framework constructs and compares four surrogate models with low sample requirements, ultimately selecting the optimal surrogate model for predicting collision force. Furthermore, a sensitivity analysis of the parameters is conducted based on the selected model, followed by a comparison with the various methods used for collision force prediction. The results illustrate the effectiveness of the proposed framework in replacing finite element models for the rapid and accurate prediction of collision force. Comparison with existing methods also underscores the advantages of the proposed framework, including low sample requirements, high calculation accuracy, and exceptional efficiency. In summary, this study not only introduces a novel and precise surrogate model framework for the swift prediction of berthing collision force, but it also offers valuable insights into the prevention of ship collision with wharf accidents and facilitates the rational and safe design of wharf structures.

“…Fu et al [2] developed a damage finite element model of a bridge span to identify and illustrate the significant difference between bridge health state and state the damage through studying the frequency response of vibration data. Yanchen et al [3] proposes a simplified analytical mode for ship-bridge collision events, which is able to predict the time-history of impact loading on bridges with sufficient precision when the basic structural frequency of the bridge pier is under 3 Hz. Comparing the test results with the finite element calculations, Sitong [4] obtained the mathematical expression of the vehicle bridge impact spectrum by fitting the period displacement amplification factor curve with a mathematical method.…”

Based on finite element method, combined with numerical simulation, the calculation algorithm of ship-bridge collision effect is given. The general formula of impact force is derived at first. Then, in order to obtain the functional relationships between ship speed, ship weight and collision force, a four continuous rigid frame highway channel bridge is taken as an instance of real bridge, the influence of ship weight and ship speed on the impact force during the ship bridge collision was analyzed. By using ANSYS / LS-DYNA software, the three-dimensional simulation dynamic finite element model of ship bridge collision was established. Numerical simulation calculations were carried out for the crest value of impact force of the ship bridge under the above two factors. Subsequently, statistical fitting analysis was carried out on calculation results. Based on numerical simulation results, the linear function relationships between the crest value of impact force and the secondary root of the ship weight and the ship speed are obtained, which provides a basis for the crest value of impact force in bridge anti-collision design.

In Northeast China and the areas along Sichuan-Tibet railway, collision between floating ice and piers of railway bridges seriously threatens the train operation safety. The safety of high-speed train running on the bridge subject to the impact of floating ice collision is rarely assessed considering the spatial interaction of the train-track-bridge-ice system. To evaluate the running safety and ride comfort of trains and the structural stability of railway bridges under the collision between floating ices and piers, a train-track-bridge (TTB) dynamic interaction model considering the impact of floating ice is established. Using the refined finite element model, the collision process of floating ice on bridge pier is simulated, and the impact loads are employed as the excitation input of the TTB dynamics model. Taking a 5 × 32 m simply-supported bridges as a case study, the influence of bridge structural parameters on the floating ice collision system is investigated, and then the dynamic responses of the TTB system induced by the floating ice impact loads are analyzed in detail. Finally, the effect of the ice impact loads on the running safety of the high-speed train is revealed. Results show that under the floating ice impact loads, the angle of the pier sharp-nose (APSN) and lateral stiffness of foundations are the key parameters that influence the dynamic responses of the bridge, and an improperly small lateral stiffness of foundation would lead to an instability of bridge structure. The influence of ice impact loads on the dynamic responses of the train is remarkable. The lateral vibration acceleration, derailment factor and lateral wheel rail force caused by the ice impact loads are all greater than those caused by the track irregularity, while the wheel unloading rate is slightly smaller. In addition, the running speed of train is also closely related to the running safety and ride comfort when the collision occurs. When the train speed exceeds 400 km/h, the train passing through the bridge would have the possibility of derailment.
