van Dijk, Bob (author)In the Netherlands, numerous bridges face reassessment. During this assessment, it is observed that in some cases, the applied shear reinforcement (stirrups) does not meet the detailing requirement given in the national annex of the NEN-EN 1992-2. This requirement, which states that the stirrups must enclose the longitudinal reinforcement to...master thesis 2024

Jonker, R. G. (author), AlYousif, A.Y. (author), Hofland, Bas (author), Antonini, A. (author), Zoon, Arthur (author), Smith, Gregory (author)This study treats a detached homogenous low-crested structure (HLCS) made of Cubipod concrete elements placed seaward of a vertical wall (forming a basin in between) to reduce overtopping. Assessing the complex hydrodynamics and effects of changing the geometry of such a system in relation to overtopping reduction is challenging. The...journal article 2024
