Slender iron column reinforced by FRP is sensitive to buckling phenomenon, taking place obviously at a cross-section within the middle segment. An equivalent FRP-iron cross-section can be used to derive the buckling resistance of the composite member by using buckling formulation previously defined for column members. [less ▲]

This paper presents numerical and analytical investigations on iron columns under axial compression, strengthened with high modulus carbon fibre reinforced polymer (FRP) sheets. Numerical and analytical models are proposed to predict the resistance and stability load of such elements, including effects of section and member geometrical imperfections and of the nonlinear characteristic and the anisotropy in post elasticity of iron material. It is shown that axial resistance and stiffness of iron columns can be increased significantly with the use of longitudinal FRP sheets as a result of the reduction of the column slenderness, but also that transverse FRP sheets should also be used to avoid any local buckling of the longitudinal FRP sheets during loading.

Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional loading, i.e. other accidental loads than those already taken into consideration in the design process. According to Eurocodes and some other national design codes, the structural integrity of civil engineering structures should be ensured through appropriate measures but, in most of the cases, no precise practical guidelines on how to achieve this goal are provided. Even basic requirements to fulfil are generally not clearly expressed. An European RFCS project called “Robust structures by joint ductility” has been set up in 2004, for three years, with the aim to provide requirements and practical guidelines allowing to ensure the structural integrity of steel and composite structures under exceptional loading through an appropriate robustness. This project involves analytical, numerical and experimental investigations; in particular, one substructure test simulating the loss of a column in a composite building, because of an unexpected impact, was performed in September 2006 at the University of Liège. This paper describes the experimental test carried out at the University of Liège, as part of this European project, and the first interpretation of the results. [less ▲]

In view of recent disasters and their immense economical and human consequences more and more focus is given not only on the safety of structures - to reduce the risk for the life of people by collapse even under exceptional loading – but on minimizing the disastrous results and to enable a quick rebuilding and reuse. One crucial mean to achieve this aim is the design of redundant robust structures. Robustness prevents the collapse of the total structure when only parts of the structure are damaged or destroyed. To avoid progressive failure, redundant structures with inherent sufficient ductile behaviour allowing deformations when a local failure occurs, have to be built. Redundancy can be achieved by allowing force redistribution within a structural system. Therefore the single sections and joints have to be especially designed and optimized, not necessarily requiring additional fabrication costs. But until now no specific rules for robustness by ductile joints exist. The aim of the present project is to define general requirements for ductile joints as part of a structural system subjected to exceptional unforeseen loading. [less ▲]

La rédaction d’une législation européenne pour le calcul et le dimensionnement des structures du génie civil, entamée à la moitié des années ’70, est en voie de finalisation. Sous peu, divers Eurocodes structuraux seront publiés sous leur forme définitive et accompagnés de leur annexe nationale, complément indispensable à leur application en Belgique. Il en sera notamment ainsi de l’Eurocode 3, consacré aux structures en acier. Si les nouvelles normes font appel à bon nombre de concepts connus, elles préconisent également des approches de calcul soit novatrices, soit plus larges au niveau de leur champs d’application. Les différences substantielles entre la version définitive (EN) et la version précédente (ENV) de l’Eurocode 3, ainsi que la publication des modalités d’utilisation pour la Belgique (Annexe Nationale), justifi ent la décision prise ces dernières années par le Centre Information Acier d’organiser régulièrement des formations à la conception et au dimensionnement de bâtiments en acier. Dans un premier temps, ces formations se sont limitées à la présentation du contenu de l’Eurocode 3, d’abord dans sa version ENV (en 1998), puis dans sa version EN (en 2004). Mais il est rapidement apparu qu’une démarche plus ambitieuse encore devait être suivie, dont l’objectif serait de mettre davantage l’accent sur les aspects pratiques de conception et de dimensionnement. Une approche pédagogique nouvelle a dès lors été développée et mise en oeuvre, à la satisfaction de tous, à l’occasion de formations à l’Eurocode 3 organisées récemment à Luxembourg (printemps 2005) et à Paris (automne 2005). Le principe consiste à partir d’exemples d’application concrets et de les analyser, étape par étape, en abordant dans le détail la diversité des possibilités de calcul offertes par le document normatif, leur mise en oeuvre et les conséquences de la sélection de l’une d’entre elles dans une situation précise. Lors de ces formations récentes, deux structures et plusieurs variantes ont été choisies comme références : Structure 1 : ossature rigide contreventée à assemblages articulés - Variante A : assemblages semi-rigides - Variante B : comportement à l’incendie - Variante C : poutre de toiture en profilé reconstitué soudé Structure 2 : ossature souple non contreventée à assemblages semi-rigides Ces exemples d’application ont été préparés, au départ, dans le cadre d’un projet européen coordonné par l’Université de Liège, qui visait à la rédaction d’un manuel d’utilisation de l’Eurocode 3, dans sa version ENV. Ils ont ici été revus à la lumière de la version définitive EN de l’Eurocode. Suite à de nombreuses demandes reçues depuis lors par le Centre Information Acier, ces exemples d’application ont été publiés une première fois en 2006 et font l’objet aujourd’hui d’une seconde édition.
