Steel–timber composite structures offer a sustainable alternative to conventional beams by combining the high strength of steel with the circularity and workability of timber. When paired with demountable shear connectors, the system activates composite action and enables full reusability of each component, further enhancing its environmental performance. However, the timber slabs and the complex load–slip behavior of the demountable connectors present design challenges that are not yet addressed by existing guidelines. Building on a previously presented strain‐controlled method to determine the bending capacity of steel–timber composite beams, this study extends the validation of the method by analyzing various steel profiles and grades in combination with laminated veneer lumber (LVL) slabs connected via demountable shear connectors. The procedure yields bending moment resistance curves as a function of the degree of shear connection. Based on the existing degree of shear connection, the specific bending capacity is determined and compared with results from finite element simulations using ABAQUS. The safe‐sided results of the strain‐controlled method confirm its reliability and supports its potential integration into design guidelines.
The growing pressure to decarbonise the construction industry has increased interest in structural systems that combine timber with other materials. Steel frames combined with mass‐timber floors, such as cross‐laminated timber (CLT), have been investigated as low‐carbon and lightweight solutions with strong reuse poten...
