TNO Bouw en Ondergrond (author), van den Berg, G. (author), Fellinger, J.H.H. (author), Soetens, F. (author)In this article, a methodology is presented by which the structural behaviour of composite steel framed building under natural fire conditions can be analysed. As a first step, a fire model is employed in order to predict the temperature development in the fire compartment. Secondly, a thermal response model is used to calculate the temperature...conference paper 2005

Soetens, F. (author), van Straalen, IJ.J. (author), TNO Bouw (author)Applications of aluminium have grown considerably in building and civil engineering the last decade, which is due to various aspects: light weight, durability and maintenance, use of extrusions. The paper starts with a short history of aluminium bridges and then focuses on aluminium bridges in the Netherlands. The design of 58 bridges for an...conference paper 2004

Maljaars, J. (author), Soetens, F. (author), van Straalen, IJ.J. (author), TNO Bouw (author)De gunstige sterkte-gewichtsverhouding en de duurzaamheid van aluminium maken het bij uitstek geschikt als constructie-materiaal voor beweegbare (verkeers)bruggen of voor de vervanging van houten brugdekken. Voor een materiaal met een dergelijk laag eigen gewicht geldt echter dat het gevoelig is voor vermoeiing, aangezien de variabele belasting...article 2004

Maljaars, J. (author), Soetens, F. (author), van Straalen, IJ.J. (author), TNO Bouw (author)Traffic bridges are subjected to variable loads and should therefore be checked on fatigue. Especially low weight materials, like aluminium, are sensitive to fatigue, because the variable load is a substantial part of the total load. This paper shows the structural design of an aluminium bridge loaded by heavy traffic. The S-N curves of a welded...conference paper 2004

Botter, H. (author), van den Berg, A. (author), Soetens, F. (author), van Straalen, IJ.J. (author), Vogelesang, L.B. (author), TNO Bouw (author)Using two types of adhesively bonded aluminium joints, a TAST specimen and a specifically designed stiff double lap joint, experiments show that the (apparent) yield stress, the amount of plastic flow and the occurence of strain hardening is influenced by the surface pre-treatment used for an Al-Mg-Si aluminium alloy adherend. Grit blasted...conference paper 2001

van den Berg, A. (author), Botter, H. (author), Soetens, F. (author), Vogelesang, L.B. (author), TNO Bouw (author)To accurately predict failure of adhesively bonded joints, it is necessary to distinguish between the different failure modes and failure criteria that can occur. In order to do so and to verify theoretical results with experimental results, joints must be available that exhibit these different failure modes. Therefore, a test programme has been...article 2001

Mennink, J. (author), Soetens, F. (author), Snijder, H.H. (author), van Hove, B.W.E.M. (author)The extrusion manufacturing process of aluminium allows protiles with a large variety of cross-sections. If these are thin-walled. cross-sectional instability miszht occur, which is caused by interaction of local buckling modes of connecting plate elements. To investigate this phenomenon. an extensive set of experiments is performed on uniformly...conference paper 2000

Soetens, F. (author), Mennink, J. (author), TNO Bouw (author)The design of aluminium structures in building and civil engineering applications is different from designing in traditional materials. This difference is based on the physical and mechanical properties of the material and the freedom of cross-sectional shape provided by the extrusion manufacturing process. This freedom of shape is a key to...conference paper 1999
