ORBi Open Repository and Bibliography (313.923 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  3. Design methods to assess the resistance of Offshore wind Turbine Structures impacted by a ship

    Echeverry Jaramillo, Sara; Le Sourne, Hervé; Bela, Andreea; Pire, Timothée; Rigo, Philippe
    The dynamic modes of jacket, monopile and Floating offshore wind turbines (FOWT) after a collision event are presented. The authors have developed simplified analytical formulations based on plastic limit analysis to assess the resistance of an offshore wind turbine jacket impacted by a ship. For the case of collisions with monopile foundations and FOWT, the crushing behavior and structure dynamics are studied by means of finite element simulations. Numerical results for both monopile and floating structures will serve for further developments of simplified analytical tools, similar to that used for jacket structures.

  4. Ship collision analysis on Offshore Wind Turbines with monopile foundations

    Bela, Andreea; Le Sourne, Hervé; Rigo, Philippe
    Every year the offshore wind industry is expanding and new offshore wind farms are built in deeper waters and closer to the traffic lanes for commercial and passenger ships leading to possible collision events. The consequences of such events can range from minor structural damage to collapse of the Offshore Wind Turbine (OWT), with probability of ship sinking, pollution and at worst, to loss of human lives. Therefore, a collision risk analysis becomes a necessity in the pre-design stage of an offshore wind farm in order to identify the collision scenarios having the greatest probabilities of occurrence but also the...

    Presentation of results of the OPTIBRI research work. The two topics of Fatigue and Buckling within composite bridge are focused and three case studies of a highway bridge are presented using two different steel grades and adapted design guidelines.

  9. Mixture model in high-order statistics for peak factor estimation on low-rise building

    Rigo, François; Andrianne, Thomas; Denoël, Vincent
    To design reliable structures, extreme pressures and peak factors are required. In many applications of Wind Engineering, their statistical analysis has to be performed taking into account the non-Gaussianity of the wind pressures. With the increasing precision and sampling frequency of pressure sensors, large short and local peak events are more usually captured. Their relevance is naturally questioned in the context of a structural design. Furthermore, the increasing computational power allows for accumulation and analysis of larger data sets revealing the detailed nature of wind flows around bluff bodies. In particular, in the shear layers and where local vortices form, it...

  10. VIV response of a suspended sphere nearby the critical Reynolds number

    Andrianne, Thomas; Rigo, François; Denoël, Vincent
    The Vortex-Induced Vibration of a sphere connected to a flexible beam is investigated in air for Reynolds numbers including the critical value. For this value (ReC =3e5 ), wake disorganisation is expected in a static configuration. This fundamental fluid-structure interaction characterised by an axisymmetric configuration leads to vibrations in the lateral and longitudinal directions. Similarly to the well-known circular cylinder, a lock-in phenomenon will take place due to the effect of the motion of the body on the shedding process. An experimental aeroelastic model is designed, instrumented and tested in the wind tunnel of University of Liège. The objective is...

  11. Vortex induced vibrations of rectangular cylinders arranged on a grid

    Rigo, François; Andrianne, Thomas
    A grid arrangement made of one hundred rectangular cylinders fixed to the facade of a house generates strong and disturbing mono-harmonic noise. The cross-flow vibration of the rectangular cylinders is identified as the origin of the noise. The present article proposes a complete investigation of the Vortex Induced Vibration (VIV) combined with a grid effect. It is based on in situ measurements, numerical (finite elements and Computational Fluid Dynamics (CFD)) and extensive wind tunnel (WT) modelling. A comparison between unsteady pressure tap measurements and CFD results allows to understand the vortex shedding process and synchronisation type depending on the wind...

  12. Schéma Directeur pour l'aménagement de la RN 51 entre Quiévrain et Mons

    Cardyn, Amélie; Blieck, Gauthier; Hanocq, Philippe; Weber, Lidvine; Van Pestel, Alexandre
    La N51 entre Mons et Quiévrain est un axe historique qui traverse le Borinage et qui constitue l'accès privilégié à ce bassin de vie. Dans le cadre de la revitalisation de la région, l’Intercommunale de développement économique et d'aménagement du Coeur de Hainaut (IDEA scrl) souhaite donner à ce tronçon une image et une dynamique nouvelles. A juste titre, la mission ne se limite pas à la mobilité mais implique également une réflexion sur l’aménagement du territoire et le cadre de vie.

  13. Expropriation et reconnaissance de zone pour l'aménagement de la zone d'activité économique des Hauts-Sarts 4 Oupeye/Herstal

    Bredo, Raphaël; Hanocq, Philippe; SEREMET, Mariana
    Le projet vise à permettre l'extension de la Zone d'Activités Economiques des Hauts-Sarts sur +/- 60 ha. Le projet porte sur une enclave située entre l’actuel parc industriel des Hauts-Sarts (500 Ha / 9.000 emplois) et les noyaux d’habitat d’Oupeye et de Hermée. Le dossier prend en compte les principales contraintes du site (environnement, mobilité, planologie, ...) et propose des solutions d'aménagement optimalisées en fonction de ces paramètres, tout en répondant au programme du développeur.

  14. Safety on intermodal hubs – The case of the Liège-Guillemins railway station

    Hanocq, Philippe; Dufert, Guillaume
    The study focuses on insecurity problems posed by an extremely important intermodal hub at the scale of the city of Liege. It is based on a double analysis : - firstly on a statement of objective insecurity identified in the station and its surroundings by the police between 2007 and 2015 ; - secondly on a survey on the feeling of insecurity (subjective insecurity) conducted in 2015 by the operator of the station (SNCB – Belgian National Railway Company).

  15. Review of urban flood experimental models and preliminary design of a laboratory setup of urban flooding

    Li, Xuefang; Erpicum, Sébastien; Archambeau, Pierre; Pirotton, Michel; Bruwier, Martin; Dewals, Benjamin
    In this study, we will investigate a study on an urban flood experimental model. Firstly, a literature review of urban flood experimental models is addressed to summarize the studies in this sector (Section 2). Next, a strategy of experimental model design will be proposed (section 3.1). Particularly, we are interested in analyzing the influence of model distortion to the flow characteristics (Section 3) and the effect of the interaction between surface flow and underground space (Section 4).
