Abstract

Aiming at the dual challenges of high carbon emissions in the global construction industry and the shortage of high-quality structural wood resources in China, this paper systematically reviews the research progress of Cross-Laminated Timber (CLT), Hybrid Cross-Laminated Timber (HCLT), Laminated Veneer Lumber (LVL) and glued bamboo (Glubam), with a focus on analyzing the mechanical performance optimization and engineering application status of bamboo-wood composite structures. Studies have shown that although fast-growing poplar LVL can effectively improve the utilization rate of fast-growing wood, its mechanical properties are still difficult to meet the requirements of high-end structures; while Glubam glued bamboo has become an ideal structural reinforcement material due to its excellent strength-to-weight ratio and environmental protection characteristics. Based on this, this paper innovatively proposes a new bamboo-wood composite structure scheme using fast-growing poplar LVL as the core layer and high-performance Glubam as the reinforced outer layers. This scheme can give full play to the performance complementary advantages of the two materials and significantly improve the overall mechanical properties of the composite material. The research results provide a new idea for the high-value utilization of bamboo and wood resources in China, and have important theoretical significance and engineering value for promoting the sustainable development of the green building industry.
