COMPARATIVE APPROACH IN THE DIMENSIONING AND THE THEORETICAL AND NUMERICAL STUDY OF COMPOSITE BEAMS, STEEL-CONCRETE AND STEEL-WOOD (CLT FLOOR)

Abstract

This theoretical study aims to study to what extent composite beams combining a steel profile and a cross-laminated timber (CLT) floor are convenient. This construction technique is inspired by the “traditional” composite beams which use a steel section and a concrete slab which have already proven themselves in multi-storey buildings. If we manage to use this technique by replacing the concrete with a product derived from wood, we can then expect a better ecological balance, a reduction in the weight of the structure, more prefabrication and the possibility of dismantling/reusing the structure. The ultimate goal is to be able to compare a traditional mixed steel/concrete floor with a steel/CLT floor and see if this new way of building a floor can really succeed. Recent research has been conducted on possible connections between steel profiles and CLT panels to examine their potentials in composite construction. Based on the aforementioned statements, we therefore present the main conclusions that have been drawn.
