“…The significant effects of the different boundary conditions of impacted bridges at the top affected by the inertia of overlaying superstructures [54,66] and at the bottom surrounded by soil layer [53,61,64,[116][117][118][119] were explored in the literature. The substantial influences of bridge superstructure on the impact responses and failure behaviors of the impacted pier especially on the location of plastic hinge formed in the pier columns were concluded by Gholipour et al [52].…”

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.

“…Darüber hinaus wurden zum Schutz der Brückenpfeiler verschiedene Vorrichtungen entwickelt und umgesetzt, die einen direkten Schiffsanprall vermeiden und die Pfeiler diesbezüglich quasi isolieren. Gängige Schutzvorrichtungen sind beispielsweise "artificial islands" [5], "guiding structures" [6], "dolphin structures" [7,8] und "floating structures" [9,10]. Da solche Konstruktio-nen häufig mit vergleichsweise hohen Kosten und recht großen Herausforderungen bei der Erstellung bzw.…”

Numerische Untersuchungen einer energiedissipierenden Schutzvorrichtung gegen Schiffsanprall

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.

“…For example, Zhou et al (2020) proposed a new type of assembled ultra-high performance concrete (UHPC) collision avoidance, which could reduce the collision force between shipping vessels and bridges, prolong the collision time, and protect the vessels as well. Wang and Morgenthal (2019) studied an independent protective structure supported by concrete-filled steel pipes, which could protect piers from barge collision by absorbing the energy through plastic deformation. Another new vessel collision protection device made of drilled shafts, which was designed by Pinto et al (2018), could absorb vessel collision energy through the plastic deformation of shafts.…”

A new type of pier anti-collision composite structure composed of honeycomb steel and polyurethane (PU) elastomer was proposed in this study. The impacts of the shape and filling materials of inner core cells on the failure mode, load–displacement cure, bearing capacity, structural stability, and energy absorption were studied by conducting uniaxial compression tests on device segments. Test results showed that the bearing capacity, structural stability, and energy absorption of honeycomb steel structure were significantly improved by PU elastomer filling. Besides, when compared with the square honeycomb structure and the regular hexagon honeycomb structure, the maximum values of average load, total energy absorption (TEA), and specific energy absorption (SEA), which were 69.6 kN, 1986.1 J, and 1300 J/kg, respectively, for the regular triangle honeycomb structure without PU filling, increased to 459.3%, 376.38%, and 212.5%, respectively, for the regular hexagonal core cell structure with PU filling, which was proved to be the most suitable core structure for pier anti-collision device.
