“…In practical engineering applications, the service environment of materials is variable and complex, with several studies demonstrating that service temperatures, ranging from -40 °C to 80 °C [12], significantly affect the mechanical properties of bamboo materials [13][14][15][16]. To incorporate the effect of temperature on engineered bamboo, Gutierrez et al [17] analyzed the mechanical performance changes of bamboo scrimber at high temperatures, studied stress-strain curves of bamboo scrimber within a temperature range of 20 °C to 250 °C, and summarized the failure modes at various temperatures.…”

Laminated bamboo is a novel green building material, understanding its mechanical properties at service temperatures is essential for structural safety and optimal design. However, currently there is no constitutive model capable of effectively predicting the compressive stress-strain relationship of laminated bamboo under the influence of service temperatures. This paper examines the influence of service temperature on the stress-strain relationship in laminated bamboo. Based on the fundamental form of the Weibull cumulative distribution, a constitutive model is proposed that can simulate the stress-strain relationship of laminated bamboo under varying temperature conditions, including strain hardening and thermal softening characteristics. Additionally, four constitutive models previously successfully applied to laminated bamboo or other bamboo composites were modified and analyzed for their capability to predict the compressive stress-strain relationship of bamboo-based materials under different temperature. The findings of this study not only guide the application of bamboo-based engineered materials in actual engineering structures, enhancing the precision and safety of structural designs, optimizing material usage, reducing waste, and lowering costs, but also provide valuable references for the research and application of other bamboo composite materials.

“…Wood is a naturally growing, renewable and organic material whose mechanical properties, such as strength and elastic modulus, can meet the needs of structural use, so wood has been widely used in various structural systems. Nowadays, the world vigorously promotes prefabricated buildings and advocates the concepts of energy conservation, emission reduction and environmental protection [5], making modern wood structure buildings a major innovation in the building materials industry. Engineering wood products not only overcomes the natural wood shortage but also greatly improves the strength and utilization of wood.…”

Wood is a green material in line with the sustainable development strategy. From the excellent performance of engineering wood products, modern wood structures represented by light wood structures have gained more development opportunities. As an indispensable part of light wood structure systems, the wood-frame shear wall plays a vital role in the bearing capacity and earthquake resistance of light wood structure systems. This paper is focused on a review of the lateral performance of wood-frame shear walls and classifies the influencing factors in relevant experimental research into three categories, including internal factors such as shear wall structure, external factors such as test scheme, and other factors of material production and test process. Finally, the research prospects in this field were introduced based on the summary of the research status. This work can be a reference for further research on the lateral performance of wood-frame shear walls.
