Wu, W. (author), Veljkovic, M. (author), Kolstein, M.H. (author), Maljaars, Johan (author), Pijpers, Richard (author)Fatigue cracks in the stiffener-to-deck plate connections of orthotropic bridge decks, initiating from the weld toe or root and propagating into the stiffener or weld throat, are experimentally and numerically studied. A statistical analysis of the structural stress is carried out using the experimental data. Automatic welded specimens show a...journal article 2024

Wu, W. (author), Veljkovic, M. (author), Kolstein, M.H. (author), Pijpers, Richard (author), Maljaars, Johan (author)Steel Orthotropic Bridge Decks (OBDs) are widely used in long-span and movable bridges. Fatigue resistance analysis plays an important role in the design or assessment of OBDs. One possible fatigue failure is the crack initiating from the weld root of stiffener-to-deck plate connections at crossbeams. A full-scale experimental investigation...journal article 2024

Maljaars, Johan (author), Pijpers, Richard (author), Wu, W. (author), Kolstein, M.H. (author)This study derives the fatigue resistance of welded details in orthotropic decks using structural stress (hot-spot stress where possible) based on tests described in literature and tests by the authors. The data are supported with linear elastic fracture mechanics simulations. Details covered are the rib to deck weld, the crossbeam to deck...journal article 2023

(author), Kolstein, M.H. (author), Nijgh, M.P. (author)SIROCO investigated the slip-resistant behaviour of carbon and stainless steel preloaded connections as well as the preloading behaviour of stainless steel bolting assemblies in principle. The slip factor test procedure according to Annex G of EN 1090-2 was investigated regarding the influence of the test speed, preload level, tightening method,...report 2019

Wu, W. (author), Kolstein, M.H. (author), Veljkovic, M. (author)The orthotropic steel decks (OSDs) are widely used in bridge engineering to support traffic loads. A possible crack, initiating from the weld toe of rib-to-deck welded joint and growing into the deck plate, is studied using linear elastic fracture mechanics. A detailed FE model is created and the results are compared with the fatigue tests...journal article 2019

Akyel, A. (author), Kolstein, M.H. (author), Bijlaard, F.S.K. (author)Modern steel manufacturing techniques make it possible to produce steel with the nominal yield strength up to 1300 MPa for structural purposes. However, the application of very high strength steels is still limited in the civil engineering structures due to lack of knowledge about the effects of the manufacturing process and experimental results...journal article 2018

Wu, W. (author), Kolstein, M.H. (author), Veljkovic, M. (author)The orthotropic steel decks (OSDs) are one of the most widely used bridge components, especially in moveable and long span bridges. Numerous cracks have been detected in this type of deck in existing bridges, mainly in the welded joints. The fatigue performance of the bridge deck dominates its design. Among them, the crack at the rib-to-deck...journal article 2018

Teixeira De Freitas, S. (author), Kolstein, M.H. (author), Bijlaard, F.S.K. (author)Full-scale fatigue tests were performed on two retrofitted orthotropic bridge decks (OBDs). The retrofitting systems consist of adding a second steel plate on the top of the existing deck. The aim is to reduce the stresses at the fatigue-sensitive details and therefore extend the fatigue life of the OBD by stiffening the existing deck plate....journal article 2017
