“…Studies (Aflatooni et al, 2012; Zhou et al, 2017) have shown that RC piers could sustain different damage levels due to various vehicle impact forces, which affected subsequent service life of the impacted piers. Moreover, studies (Sharma et al, 2012; Zhou et al, 2017) have shown that the vehicle impact force was greatly affected by impact velocity and impact mass. A qualitative damage classification of the impacted pier was defined in this section.…”

“…Pham and Hao (2017) performed numerical analyses on the plastic hinges and inertia forces in RC beams under impact loads. In addition, there are also many other publications that reported numerical studies on impact behaviors of RC piers (Chen et al, 2016; Chung et al, 2014; Zhou et al, 2017). However, few numerical studies describe well the failure process and damage assessment of the impacted piers.…”

In this article, a method was proposed to assess damage of the bridge piers subjected to vehicle collision with the help of the detailed numerical model. Nonlinear material constitutive laws considering the strain rate effect were adopted in the models. Validation was performed by comparing the numerical results with the available experimental results in terms of impact force, displacement, and failure pattern. Based on the validated numerical models, the failure process and different damage levels of the piers under impacts were analyzed. The results showed a four-stage failure process as well as four damage levels with the increase of the vehicle impact force. According to the numerical study, a new damage index and the corresponding assessment criterion were defined to assess damage of the impacted pier. A vehicle impact force equation and a half-sine impact impulse were developed for damage index.

“…Do et al [17] studied the failure model and dynamic response of a bridge pier through numerical simulation and experiment. Zhou et al [18] used the parameterization method to study the collision response behavior of a vehicle hitting a bridge pier and its structural damage mechanism. Studies have shown that, after a ship hits a bridge pier, the impact resistance of the bridge structure can be improved in two ways: one is to improve the anticollision performance of the bridge, and the other is to set up an anticollision facility.…”

To reduce the loss of life and property caused by the collision of a ship against a bridge pier, this study proposes a new type of anticollision facility. The facility uses corrugated steel plates and corrugated steel pipes (CSPs), or ordinary steel plates and corrugated steel pipes (OSPs), as structural elements to form a honeycomb structure, which can greatly improve the impact resistance of bridge piers and reduce any damage to ships. To evaluate the anticollision performance of the proposed anticollision facility, this work uses the CSPs and OSPs as study objects in the impact test research. A pendulum impact test system was utilized to compare and analyze the column with CSP and OSP specimens and the column without any anticollision facilities. Test results show that the CSP and OSP specimens have a relatively high energy dissipation effect. When the impact energy is small, the energy dissipation effect of the OSPs with the same plate thickness is stronger than that of the CSPs. When the impact energy is large, the energy dissipation effect of the CSPs with the same plate thickness is stronger than that of the OSPs. In addition, the extreme value analysis method is used to analyze the relationship curve between the peak value of the D1 lateral displacement and the specimen’s plate thickness, weight, and natural frequency; the optimal thickness, weight, and natural frequency values of the CSP and OSP specimens are also deduced. Taking the optimal value of the specimen’s natural frequency as a target, the structure of the CSP and OSP specimens is optimized. When the optimized plate thickness is 2.50 mm, the ratios of the optimal value of the specimen plate thickness, weight, and natural frequency to the optimal calculation value are all in the range of [0.80, 1.12]. OSP and CSP specimens are found to have the best energy dissipation effect. The peak value of the D1 lateral displacement of the top of the column equipped with the CSPs is at least 88.37% lower than that of the column without any anticollision facilities. For the top of the column equipped with the OSPs, the peak value of the D1 lateral displacement is at least 80.37% lower than that of the column without any anticollision facilities. Optimization results show that the extreme value analysis method is suitable for the optimal design of anticollision facilities for piers.
