“…Besides, many attempts were carried out to evaluate the structural responses of bridge piers using simplified analytical methods [62,65,96,104,105], and FE high-resolution techniques [52,54,59,67,106]. In addition, several approaches were proposed to analyze the impact loads and bridge dynamic demands using shock spectrum analysis [104,[107][108][109], structural reliability analysis [55,63,[110][111][112][113][114], and equivalent static analysis [115,116] methods. Table 4 presents a summary of vessel-pier collisions with regard to the influences of various parameters.…”

Reinforced concrete structures and structural members used in strategic infrastructures such as highway bridges, high-rise buildings, etc. are inherently subjected to lateral impact loads arising from the collision of vehicles, vessels, falling rocks, and rigid objects having different impact geometries, weights, and velocities. Due to the brittle nature of concrete materials, both localized and overall failure modes are very likely to occur in concrete structures under dynamic and impulsive loads. Hence, many attempts have been carried out in the literature to recognize the failure behaviors and to assess the vulnerability of concrete structure under lateral impact loads. This paper presents a comprehensive state-of-the-art review on the responses and failure behaviors of various types of concrete structures and structural members subjected to lateral impact loads based on analytical, numerical, and experimental studies carried out by the previous research works. In addition, the influences of various structural- and load-related parameters on the impact resistance and failure behaviors of different concrete structures under lateral impact loads are reviewed.

“…The absolute sum (ABSSUM) rule performs much better for the base shear and base bending moment, but results in overestimation of the pier top displacement. Fan et al (2015) also proposed a complicated modal combination rule weighted algebraic sum (WAS) to quantify the bridge responses accurately due to barge collision based on response spectrum analysis. Here, an approximate and simple modal combination rule named square root of partial combination (SRPC) is proposed.…”

This article presents finite element simulations of bridge-barge collision using a representative Jumbo Hopper barge model and a bridge pier model with a squared cross section. Based on the simulation results and also the conservation principles of kinetic energy and linear momentum, refined simplified impact force history models for both elastic and inelastic collisions are developed. The simplified force models take into account the influences of barge impact velocity, barge loading tonnage and pier size. The proposed force models are validated through comparisons on the impact force time histories and response spectra with other impact force models. With a three-span continuous girder bridge, the participation of different bridge modal responses and modal combination rules are also investigated. A new modal combination rule is proposed for quantifying the maximum responses due to barge impact load.

An equivalent static method is employed in calculating the impact response of vessel-bridge collisions, in which the dynamic characteristics of vessel-bridge collisions are ignored. An impact response spectrum for vessel-bridge design is proposed according to the principle of the earthquake response spectrum. The impact force time-histories are obtained through a numerical simulation method using finite element software. The relationship between the displacement amplification factor of the single-degree-of-freedom, period, and damping ratio under the excitation of impact force-time histories is obtained. The regularity of the displacement amplification is summarized. The characteristics of the vessel-bridge collision are given. The three-stage expression and specific application steps of the impact response spectrum for the design of vessel-bridge collision are provided.
