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 truss is an important load-bearing component in light-weight wood structure. In order to study its mechanical properties, considering the structural characteristics and non-linearity of tooth plate connection, a finite element model of light wood truss is established. The accuracy of the model is verified by comparison with the test results of its mechanical properties. The analysis of light wood trusses with different load patterns, different heights and different configurations shows that the simulation method of the light wood trusses is simple and accurate, Good, contribute to the simulation study of light wood truss force performance, and promote the localization of light wood truss.
