This reports present a computer program to predict the bending behavior of wood based materials such as nailed built-up wood beams, two-layered wood beams connected with nails and nailed stressed-skin panels.The procedure used is a finite element method based upon the displacement method. Verification of the proposed expression is sought through the past experimental studies. Generally considerable agreement is obtained between the calculated deflections and observed ones.The results show that the computer programs in this study are capable of analyzing the bending behavior of the nailed built-up wood beams, two-layered wood beams connected with nails and the nailed stressed-skin panels.

本文提出了一个计算木基材料如钉合木梁、钉接双层木梁和钉合应力蒙皮板弯曲性能的计算机程序，所用程序是基于位移法的有限单元法。通过以往的实验研究，验证了所提出的表达式。结果表明，本文编制的计算程序能够分析钉固组合木梁、钉固双层木梁和钉固应力蒙皮板的弯曲性能。
