Numerical investigation into the effects of corrosion on the shear performance of pretensioned bridge girders with cast-in-place slabs
(Peer reviewed; Journal article, 2022)Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance ... -
Numerical Investigation of a Post-tensioned Flat Slab with Steel Fibre Reinforcement
(Master thesis, 2013)This study consists of a numerical investigation of a post-tensioned flat slab without conventional longitudinal reinforcement; only steel fibres were employed to ensure sufficient ductility and shear capacity of the slab. ... -
Numerical Investigation of Focused Waves and their Interaction with a Vertical Cylinder using REEF3D
(Journal article; Peer reviewed, 2017)For the stability of offshore structures, such as offshore wind foundations, extreme wave conditions need to be taken into account. Waves from extreme events are critical from the design perspective. In a numerical wave ... -
Numerical Investigation of Irregular Breaking Waves for Extreme Wave Spectra Using CFD
