Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional events. For more than 10 years, the University of Liege is strongly involved in researches further investigating the response of structures to such exceptional events [1, 2]. The present paper gives a global overview on recent or on-going developments performed at the University of Liege in the field of robustness of steel building structures subjected to impact loading leading to the loss of a column. The conducted studies are founded on a combination of experimental, numerical and analytical approaches with the final aim to propose simplified procedures useful for practitioners and allowing ensuring an appropriate level of robustness to structures for the considered scenario. © 2017 Jean-François et al.

The paper will illustrate the contribution of research into Construction History in condition assessment or residual carrying capacity situations for three old types of concrete constructions. We will address: - the problem of assessing the actual carrying capacity of "Hennebique" reinforced concrete type beams with their characteristic reinforcement system, widespread in many countries before the First World War. - the replacement of the external post-tensioning tendons within a hollow box girder railway bridge built in the early 1960s with the "Blaton-Magnel" anchorage system developed in Belgium from 1941 onwards, and used until the early 1960s, in Belgium and abroad. - the structural assessment of thin concrete hyperbolic paraboloid shells, which were highly popular with architects and engineers in 1950s-1960s.

In Liège, the existing railway infrastructure was not capable of being properly used by high-speed trains. A number of elements handicapped the site of the old station: curved platforms that were too narrow, an approach speed to the station that was too low, numerous track intersections and poor positioning of the BrusselsGermany line, even though it carries the most traffic. In comparison with the old building, the route through the new station has been moved 150 m in order to meet two requirements: - to enable straight platforms which make it easier for trains to enter and leave the station and for passengers to embark and disembark; - to establish a harmonious link between the station and the nearby motorway network. This link with the motorway network is provided by a bridge and a viaduct, designed by Santiago Calatrava. This Hillside entrance to the station has the advantage of the availability of a carpark with 600 parking spaces, immediately next to the platforms. The station now has nine tracks and five platforms 8 m wide, thus allowing people to move around more freely. Three of the platforms, 450 m long, can accommodate double-unit HSR units. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.
