摘　　要：针对杨木—秸秆层合梁的弯曲问题,利用分层剪切理论对其变形和强度进行了分析。并将分析结果与经典理论、一阶和高阶剪切变形理论的结果进行了比较。结果表明,分层剪切变形理论用于分析杨木—秸秆层合梁弯曲问题,不但具有理论价值,而且也具有实际应用意义。Aimed at the bend of poplar-straw laminated beam,the theory of delamination shearing deformation was used to analyse its bending deflection and strength,and compared the results with other theories. The results of calculation demonstrates that the delamination shearing deformation theory used in analysis of transverse shear effect on the poplar-straw laminated beam not only has theoretic value,but also has application meaning.
