“…In conclusion, retrofitting significantly enhances the energy performance of multi-story residential buildings in Italy, resulting in a reduction of up to 60% in global energy demand. Projections indicate that global demand for mass timber will continue rising upward, particularly in Australia, Japan, and New Zealand [76]. Responding to this trend, Li et al [77] studied the out-of-plane bending behavior of Radiata Pine XLam CLT panels subjected to four-point loading.…”

Due to its inherent characteristics, such as a light weight and ease of workability, timber is ideal for prefabricated and modular construction. However, since the research in this field covers a wide range of niches such as structural engineering, building physics, design for assembly and disassembly, and life cycle analysis, among others, and since there has been considerable development of the field in past years—boosted by new mass timber products and tall timber construction—it is difficult to critically analyze the current state of the art, current trends, and research challenges. Therefore, this research aimed to cover a systematic review of 409 articles to assess the field of prefabricated and modular timber construction critically. The methodology comprised a co-word network approach using the Science Mapping Analysis Software Tool (SciMAT, Version 3) to illustrate their evolution from 1990 to 2023. The findings show that the circular economy and digital technologies significantly impact the development of these technologies, which can potentially provide practical solutions for designing buildings with a circular approach and improving productivity and efficiency in the construction process. However, it is essential to acknowledge a notable deficiency in the research and understanding of these subjects. Therefore, various sectors must take the lead in conducting a thorough reassessment to enhance research and development in the field. Finally, the findings from this research can significantly contribute to existing knowledge and serve as a comprehensive platform for the further exploration of prefabricated and modular timber construction.

“…The total number of SMTJ specimens was 5, control group specimens were designated as SJ-1, while specimens decayed for 6, 12, 18, and 24 weeks were labeled SJ-2, SJ-3, SJ-4, and SJ-5, respectively. tigated changes in the mechanical properties of cross-laminated timber connection assemblies in the presence of brown rot fungi, observing that their load-carrying capacity and energy-dissipation properties significantly decreased after 40 weeks of decay [29]. Several researchers have obtained decaying wooden frames from ancient buildings to test their precise mechanical properties and develop failure models, gaining valuable insights into the underlying mechanisms governing mechanical property degradation in decayed wood structures [30,31].…”

The straight mortise and tenon joints (SMTJs) of Tusi Manor, situated in the Yunnan–Tibet region of China, tend to undergo decay. This study aims to investigate the mechanism performance degradation of SMTJs due to decay. Five full-scale SMTJs were constructed and incubated with wood-rot fungi for 0, 6, 12, 18, and 24 weeks. Cyclic loading tests were conducted to assess the damage mechanisms and extent of mechanical property degradation at these different stages of decay, supported by ABAQUS finite element simulation software. The results revealed a progressive increase in damage with prolonged decay time. Comparison between decayed and undecayed specimens showed a maximum load-bearing performance degradation rate of 5.17%, 11.83%, 17.34%, and 23.54% after 6, 12, 18, and 24 weeks of fungal incubation, respectively. The cumulative energy efficiency degradation rates were 8.38%, 9.51%, 23.13%, and 33.31%, respectively. SMTJs mechanical performance degradation is correlated with wood mechanical property degradation as a function of the S-family. Finite element simulations further indicated a reduction in tenon strength from the outer parts towards the inner parts of the structure.
