Abstract

[en] This work aims to assess the economic benefit of using high strength steel (S460) and/or high performance concrete (C50/60) in composite steel-concrete columns. The use of high performance materials (HS materials) leads in particular to a reduction in the quantity of raw material, with equal loading. This implies the construction of a lighter structure or, while retaining the same section dimensions, structures with greater spans. The complexity of the economic interest assessment lies in the fact that many elements are involved, such as the steel profile, concrete, rebar, stirrups, labor, etc. Consequently, the variation in the quantity of raw material of concrete and steel, being the main factor of the presence or not of an economic benefit, does not fully explain the results. Two studies concerning the study of the economic benefit of high performance steel have already been carried out at the University of Liege: one concerning composite structures and the other concerning steel structures. These studies have in common the fact that they only considered HS steels. Consequently, the objective of this thesis is on the one hand, to integrate HS concrete in an economic study of this kind and on the other hand, to extend research for HS steels. Consequently, the designer can, on the basis of this work, determine if there is an economic benefit in using HS materials for a composite column or not, for a column length and a compression load known.
