| 摘 要： | 空腹钢管桁架结构在实际工程中应用非常普遍，T型相贯节点的平面内抗弯刚度对结构的受力性能有很大影响。以空腹桁架中的平面T型节点为研究对象，采用通用有限元软件ANSYS对其抗弯刚度和极限承载力进行计算，得到各无量纲参数与T型节点平面内抗弯刚度之间的关系。通过与国内外现有计算公式的对比，给出T型钢管节点刚度判别的参考方法。

| Abstract: | Vierendeel tubular trusses are widely used in actual projects because of its concise appearance. However, the in plane flexural behavior of T joints has great influence on the mechanical property of steel vierendeel trusses. The general finite element software ANSYS is used to analyze the flexural rigidity and ultimate capacity of T joints. The relationship between nondimensional parameters and its in plane flexural rigidity is obtained. The flexural rigidity assessment method of T joints is proposed through comparison of finite element results and the results from current domestic and foreign criterions. |
