摘　　要： 轻型木桁架是轻型木结构中重要的承重构件,为了研究其受力性能,考虑齿板连接的构造特点及非线性特性,建立了轻型木桁架的有限元模型。通过与其受力性能的试验结果对比,验证了模型的准确性;对不同荷载模式、不同高度、不同构造形式的轻型木桁架的分析表明,轻型木桁架有限元模型的模拟方法操作简便、精度较好,有助于轻型木桁架受力性能的模拟研究,并推动轻型木桁架的国产化。 Light wood trusses are important structural components in light wood frame construction. Formation and nonlinear behavior of truss plate joints were taken into consideration to develop a finite element （FE） model for the light wood trusses. The FE model was validated by comparing predicted results with testing results and then used to predict structural behavior of light wood frame trusses with other configurations such as load patterns, truss heights and truss formations. The FE model was easy to learn and showed good accuracy. The FE modeling method could contribute to further investigation of structural behavior of light wood trusses.
