Bibliometric analysis of studies on structural timbers in Türkiye and thematic evaluation of experimental research

This study presents a comprehensive analysis of Türkiye's scholarly contributions to mass timber research by examining both bibliometric patterns and experimental studies. A PRISMA-guided screening process was applied to identify 50 studies published between 2015 and 2025, and SciMAT software was used to map thematic structures and detect conceptual shifts over two periods (2015–2020 and 2021–2025). The thematic evolution analysis shows a transition from material-centred research themes such as bonding performance, the mechanical behaviour of GLT and CLT, and durability to performance-based and system-oriented concepts including seismic behaviour, hybrid strengthening, and structural applications. The evaluation of 38 experimental studies highlights a growing emphasis on adhesives, shear performance, beam behaviour, and CLT-GLT structural systems, reflecting Türkiye's increasing interest in engineered wood products in the post-earthquake context. These findings provide new insights into the intellectual development of timber research in Türkiye and support the journal's focus on engineered wood technologies and performance-based applications.
