| Abstract: | 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. |
