“…Firstly, Jelušiˇ and Kravanka [18] assessed the optimization design of timber floor joists for a given imposed load and span of the structure. Then, De Vito et al [19], who developed a topology optimization of Douglas Fir GL 24h beams, considering the orthotropic nature of wood and the layering manufacture. Whereas Kilincarslan and Turker [20] considered the strengthening of the GL 24h spruce timber column-beam connection with carbon fiber-reinforced polymer through experimental evaluation.…”

The construction industry has a notable negative impact on the environment; thus, the promotion of the use of timber structures is an alternative to mitigate its effects. The research develops an artificial intelligence-based decision approach in the calculation of timber structures focused on the enhancement of the sustainability of roof structures. Based on the optimization carried out through genetic algorithms and the framework established in Eurocode 5, a general set of equations has been proposed for a laminated timber roof structure. The tool, which determines the most suitable roof structure for each strength class of laminated timber, allows for the determination of the dimensions of beams and purlins and their respective separations in order to minimize wood consumption. The ultimate goal is to offer multiple solutions regarding strength classes and structural designs in order to foster informed sustainable choices that promote efficient use of resources in construction.

“…Among a wide variety of distinct types of structures, those made of glue laminated timber (GLT) are especially suitable for structural optimization. Research devoted to this problem concerns shape optimization of load bearing elements (Mayencourt and Mueller, 2020;de Vito et al, 2023), optimization of the structural layout (Hua et al, 2020), combined shape and layout optimization ( Šilih et al, 2010;Kravanja and Žula, 2021) and also multiple aspects of optimal material usage (Mayencourt and Mueller, 2019;Pech et al, 2019). With regard to composite structures exploiting advantageous mechanical properties of wood, a common solution is to combine solid wood or GLT girders with top reinforced concrete (RC) slabs -reviews on the topic of Timber-Concrete Composites (TCC) can be found in (Clouston and Schreyer, 2018;Dias et al, 2018).…”

The paper presents a beam theory for composite girders consisting of two beams joined together with an adhesive layer. The height of the bottom beam is considered variable. The governing equations are suitable for formulation of a shape optimization problem in terms of control theory. The use of Pontryagin's maximum principle enables finding an optimal solution satisfying necessary optimality conditions. The presented optimization approach allows for including issues which cannot be accounted for by commercial topology optimization software. The introduced theory provides an estimated solution, which is then validated by an analysis of a 3D finite element model.
