Influence of residual stresses on the global buckling resistance of cellular and castellated members Universiteit Gent
Cellular and castellated steel members are usually made starting from a hot-rolled I-section member, of which the web is thermally cut according to a certain pattern. Subsequently, the obtained halves are welded together. Thus, a member with a larger depth and with circular or hexagonal web openings placed regularly along its length is obtained. In the past, it has been shown for hot-rolled I-section members that residual stresses have a ...
Global Buckling of Castellated and Cellular Steel Beams and Columns Universiteit Gent
Tackling the Anglophones’ free ride: Fair linguistic cooperation with a global lingua franca KU Leuven
In science and in all other domains that require communication across borders, we need one lingua franca, and this lingua franca will be English. The adoption of the native language of some as everyone's lingua franca unavoidably raises a problem of justice in various senses. One of these is cooperative justice, the fair distribution of the cost of producing a public good. This article proposes a criterion of fair burden sharing - ...
Local buckling of curved steel girder webs Universiteit Gent
Experimental investigation of the buckling behaviour of textile reinforced cement sandwich panels with varying face thickness using Digital Image Correlation Vrije Universiteit Brussel
Sandwich panels with Textile Reinforced Cement composite (TRC) faces are promising structural elements for construction, as both the structural and insulating performance are merged into one lightweight construction element. In the literature, extended research has been performed to understand the bending behaviour of TRC sandwich panels, yet research into their behaviour under axial loading is scarce. Therefore, axial compression tests on TRC ...
Lateral torsional buckling of cellular steel beams Universiteit Gent
Present paper deals with the behavior of so-called cellular members against lateral torsional buckling. These beams comprising regularly-spaced web openings are especially used for their high resistance-weight ratio, the possibility to integrate service pipes within their height, and aesthetics. Such profiles usually exhibit a complex behavior, since they can experience many modes of failure, including local instability ones, i.e. those ...
Structural Fire Performance of Concrete-Filled Built-Up Cold-Formed Steel Columns Universiteit Hasselt
Concrete-filled composite columns are widely used in the construction industry, exploiting the benefits of combining steel and concrete, providing, for instance, high load-bearing capacities and enhanced fire resistance. These solutions are extensively used in high-rise buildings and/or when high fire resistance performance requirements are imposed. In this exploratory research, a new type of concrete-filled composite column is investigated ...
EFFECTIVE BENDING STIFFNESS OF HEAVY STEEL-CONCRETE COMPOSITE COLUMNS WITH MULTIPLE ENCASED STEEL PROFILES Universiteit Hasselt
Concerning the structural analysis of steel-concrete composite columns, Eurocode 4 foresees only cross-sections with one implemented steel profile and double symmetry. However, an application of composite columns with more than one embedded steel profile can be recognised. The common practice of analysis of such columns uses the simple Euler-Bernoulli beam theory to describe the global behaviour. The performed tests and other available test ...
Shear strength of trapezoidal corrugated steel webs for horizontally curved girder bridges Universiteit Gent
Curved composite girder bridges with corrugated steel webs (CSWs) have already been constructed around the world. However, limited work has been done on their shear behavior. In this paper, the corrugated steel web (CSW) in horizontally curved girders (HCGs) is treated as an orthotropic cylindrical shallow shell, and the analytical formula for the elastic global shear buckling stress is deduced by the Galerkin method. Calculation tables for the ...
