“…Zahlreiche Bauwerke queren schiffbare Wasserwege mit einem entsprechenden Gefährdungspotenzial für den Anprall von Fracht-und Containerschiffen, das sich durch eine stetige Steigerung des Ladevolumens zunehmend vergrößert. Da derartige Anprallunfälle keine Ausnahmeerscheinung darstellen, wurden in den letzten Jahren grundlegende Untersuchungen zur Quantifizierung der Anpralllasten sowie zur dynamischen Reaktion der Bauwerke durchgeführt [1][2][3][4]. Darüber hinaus wurden zum Schutz der Brückenpfeiler verschiedene Vorrichtungen entwickelt und umgesetzt, die einen direkten Schiffsanprall vermeiden und die Pfeiler diesbezüglich quasi isolieren.…”

Herrn Univ.‐Prof. Dr.‐Ing. habil. Frank Werner zur Vollendung seines 70. Lebensjahres gewidmet Ein Schiffsanprall stellt eine außergewöhnliche Beanspruchungssituation dar, die die Sicherheit von Brückenbauwerken im Bereich von Wasserstraßen gefährdet. Zur Vermeidung des unmittelbaren Anpralls gegen Brückenpfeiler kommen unterschiedliche Schutzvorrichtungen zum Einsatz. Derartige Schutzsysteme dissipieren einen Großteil der Anprallenergie durch die Entwicklung plastischer Deformationen, sodass die vom Pfeiler bzw. Schiff zu absorbierende Energie auf ein Minimum reduziert wird. In diesem Beitrag werden numerische Untersuchungen und das strukturelle Verhalten einer neuartigen kollisionssichernden Konstruktion vorgestellt, bei der sich beim Anprall plastische Mechanismen in klar definierten Bauteilbereichen entwickeln und übrige Konstruktionselemente im elastischen Zustand verbleiben. Da die Konstruktion nach einem Anprallereignis dadurch in weiten Bereichen nicht geschädigt ist, können sich Wiederherstellungsmaßnahmen auf lokal begrenzte Bereiche beschränken. Die konstruktive Durchbildung von Konstruktionsdetails steht bei den Untersuchungen nicht im Mittelpunkt und soll in weitergehenden Studien entwickelt werden.

The development of the highway traffic has promoted the construction of increasing numbers of river-crossing bridges, but at the same time, large-size ship causes serious threat to structural safety of the bridge. The probability of bridge-ship collision increases, water safety accidents have happened frequently in the recent years. Arch bridge is easier to be subjected to the threat of ship collision because of small navigation clearance on both sides. However, study on the destructive consequences by ship impact on arch bridge is seldom. This paper takes reinforced concrete arch bridge as an example, on the basis of the forecast of the water-level frequency, flow velocity and long-term navigation density of the ship, the ship collision probability on different parts of the arch ring at different water levels are analyzed to deduce the annual collapse frequency of the grand bridge. The risk matrix evaluation result shows that there is medium risk in longterm. The establishment of finite element numerical model concludes the energy absorption and the change process when the arch ring suffers from collision from the ship under different working conditions as well as the relationship among the impact force, crown displacement and collision depth along with time change. According to the result of simulated analysis, the maximum collision force of the main arch ring suffered from the ship is 25.9MN, and the resistance of the main arch ring is 33.6 MN, so the existing structure basically meets the requirement for fortification against the ship collision. The numerical simulation results are qualitatively consistent with the risk of evaluation. The results of the analysis can provide scientific foundation to the maintenance and management of the arch bridge.

“…In the provisions by American Association of State Highway and Transportation Officials (AASHTO, 1991(AASHTO, , 2009), a simple equivalent static force model is specified to quantify barge impact load based on early studies (AASHTO, 1991(AASHTO, , 2009Meier-Dornberg, 1983). This simplified approach is unable to adequately capture the inherent dynamic character of the barge-bridge collision process including the influence of pier shape and size (Consolazio and Cook, 2002;Consolazio and Cowan, 2003;Yuan et al, 2008). On the other hand, a nonlinear impact analysis framework of vessel-bridge collision based on detailed finite element (FE) modeling is able to determine the impact force history, the collision process, and the structural dynamic response in the whole process.…”

“…Regarding the modeling of impact force, a simplified coupled vessel impact analysis (CVIA) approach was proposed by Consolazio and Cowan (2005) and Consolazio et al (2009), where a single-degree-of-freedom (SDOF) nonlinear barge model was coupled with a multiple-degree-of-freedom (MDOF) bridge model with a nonlinear spring to represent the nonlinear force-deformation behavior of barge bow during collision. However, the forcedeformation relationship of the nonlinear spring was determined via quasi-static FE simulations (Consolazio and Cook, 2003;Consolazio and Cowan, 2003), thus the material strain rate effect was not considered. The influence of material strain rate acts as a strengthening effect and cannot be neglected in the impact analysis (Jones, 2012).…”

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.
