有限元分析在正交胶合木性能研究中的应用OA北大核心

Cross-Laminated Timber(CLT),with the advantages of high stiffness,high strength,dimensional stability,excellent seismic resistance and environmental friendliness,has been widely used in the construction sector.However,many challenges exist in the test and analysis of CLT as a material and its engineering applications,such as the limited bearing capacity of its unit or structure,complex connection,insufficient fire resistance,high test cost,and the inability to directly test and analyze under extreme conditions.As a powerful numerical simulation tool,finite element analysis(FEA)plays an important role in optimizing experimental design,reducing test costs,and exploring structural responses under extreme conditions.This paper reviews the application of FEA in CLT research,focusing on mechanical performance,fire resistance,dynamic properties,and connection methods.Through an in-depth analysis of progress,results,and challenges of the current research,this paper provides a reference for further promoting the application of FEA in CLT design,optimization,and possible future research.
