从特性到应用:竹材结构设计多领域研究进展OACHSSCD

Driven by global sustainable development and China's"dual carbon"strategy,the research and development of green and low-carbon renewable materials have become an urgent need for industrial transformation and upgrading.Bamboo is an ideal alternative to traditional materials such as steel and cement because of its fast growth for timber yield in 3-5 years,high annual yields,high specific strength and strong carbon sequestration capacity.This paper reviews bamboo properties,structural design optimization and functional application progress in multiple fields.In terms of properties,the tensile strength of bamboo is 150-230 MPa,which lays a mechanical foundation for its engineering application.In terms of structural design,the focus is placed on the innovative preparation and performance enhancement mechanisms of engineered bamboo such as glued laminated bamboo and reconstituted bamboo.The review of functional applications summarizes innovative practices and application potentials of bamboo in frontier fields such as green building,modern bridge,ecological home furnishing and environmentally friendly packaging.This review aims to provide theoretical references and technical enlightenment for the value-added,functional and industrialized application of bamboo,and make a forward-looking analysis of its challenges and future development directions,thereby facilitating bamboo to become a significant bio-based material for realizing the national green development blueprint.
