    Shear strength of reinforced concrete plastic hinges subjected to seismic action
    (CRC Press, 2013-08-15)

    The shear strength of reinforced concrete beams is reduced by axial elongation of the plastic hinge regions during cyclic loading. In members with shear reinforcement this elongation may also affect the path of the shear cracks and the inclination of the compressive stress field. Thus, the effective concrete compressive strength decreases and/or the contribution of the concrete to the shear strength is reduced. This paper presents a model to predict the longitudinal strain (axial elongation) in plastic hinge regions under seismic loading at the shear failure stage. The background for this is the Cracked Membrane Model and the shear design provisions of fib Model Code 2010, respectively. The calculation procedures are based on compatibility considerations and take the longitudinal strain at mid-depth of the beam cross sections into account. The theoretical results are compared to experimental data taken from literature and in general, good correlation is found. © 2013 Taylor & Francis Group, London, UK.

    Interaction forces between huge cargo vessels and quay walls
    (CRC Press, 2013-08-15)

    The berthing maneuver of huge cargo vessels causes high reaction forces. To avoid damages to the ship and the quay walls, rubber fender systems are installed to absorb the kinetic energy of the berthing vessel. In order to analyse the entire berthing maneuver it is essential to understand the mechanics of a berthing vessel and to determine the force-deflection behavior of the rubber fenders in real conditions. Therefore, rather small rubber fenders are tested. The results of these tests can be applied to bigger identically built fenders. © 2013 Taylor & Francis Group, London, UK.
