van der Meulen, O.R. (author), Soetens, F. (author), Maljaars, J. (author)Fire is often the dominant design criterion for aluminium structures. Present design rules for aluminium constructions in fire neglect both the decrease in susceptibility to local buckling and the effects of creep, that are intrinsic to aluminium. They may therefore either overestimate or underestimate the temperature of failure, depending on...article 2014

Silitonga, S. (author), Maljaars, J. (author), Soetens, F. (author), Snijder, H.H. (author)In this work, a numerical method is pursued based on a cohesive zone model (CZM). The method is aimed at simulating fatigue crack growth as well as crack growth retardation due to an overload. In this cohesive zone model, the degradation of the material strength is represented by a variation of the cohesive traction with respect to separation of...article 2014

Maljaars, J. (author), Lukić, M. (author), Soetens, F. (author)The fatigue behaviour of aluminium shows not only many similarities, but also some differences with the fatigue behaviour of steel. There exist separate Eurocodes for the fatigue design of steel and of aluminium structures, EN1993-1-9 and EN1999-1-3, respectively. The latter standard was developed after the draft version of the first one was...article 2013

Silitonga, S. (author), Maljaars, J. (author), Soetens, F. (author), Snijder, H.H. (author)Engineering methods to predict the fatigue life of structures have been available since the beginning of the 20th century. However, a practical problem arises from complex loading conditions and a significant concern is the accuracy of the methods under variable amplitude loading. This paper provides an overview of existing fatigue damage models...article 2013

Silitonga, S. (author), Maljaars, J. (author), Soetens, F. (author), Snijder, H.H. (author)Predicting the remaining fatigue life of a structure with crack(s) is generally conducted by the fracture mechanics method. This method is aimed at predicting the crack growth and final fracture due to fluctuating loads. The crack growth curve required for these calculations is constructed on the basis of experiments. However, obtaining these...conference paper 2012

Varas, J.M. (author), Soetens, F. (author)The effect of a blast explosion on a typical steel frame building is investigated by means of computer simulations. The simulations help to identify possible hot spots that may lead to local or global failure. The blast energy is transferred to the structure by means of the façade. In particular attention is paid to the modelling of the façade...conference paper 2010

Maljaars, J. (author), Soetens, F. (author), Snijder, H.H. (author), TNO Bouw en Ondergrond (author)Design models for local buckling of fire-exposed aluminum sections are currently lacking. Based on analyses with validated finite-element models, this paper investigates local buckling of extruded sections with stress-strain relationships representative for fire-exposed aluminum alloys. Due to the fact that these stress-strain relationships are...article 2010

Soetens, F. (author), TNO Bouw en Ondergrond (author)Structural applications of aluminium are considered in this paper. Although the discussion is mainly devoted to Europe, the paper also refers, where possible, to developments in other parts of the world. The problems faced by a designer in creating an optimum design are described, followed by a brief review of the research carried out in the...article 2010

(author)The dynamic behavior of three commonly used airplane fuselage materials is investigated, namely of Al2024-T3, Glare-3 and CFRP. Dynamic tensile tests using a servo-hydraulic and a light weight shock testing machine (LSM) have been performed. The results showed no strain rate effect on Al2024-T3 and an increase in the failure strain and failure...conference paper 2010

(author)This paper gives an overview of the structural behaviour and design of aluminium structures exposed to fire conditions. Two design approaches are elaborated: the "traditional" approach that is mainly based on conventions and the fire safety engineering approach that is more based on physics. For the traditional approach, equations for the...article 2010

Maljaars, J. (author), Twilt, L. (author), Soetens, F. (author), TNO Bouw en Ondergrond (author)In order to study buckling of fire exposed aluminium columns, a finite element model is developed. The results of this model are verified with experiments. Based on a parametric study with the finite element model, it is concluded that the simple calculation model for flexural buckling of fire exposed aluminium columns in EN 1999-1-2 does not...article 2009
