本文讨论了各类平行弦塔架与截角锥塔架在扭矩作用下应力与位移的计算,给出了新的计算公式,其形式与薄壁杆件的受扭计算公式相似.并由模型的试验与有限元分析证明公式是正确的.
This paper discusses the calculation of stress and displacement of various types of parallel chord towers and truncated cone towers under the action of torque, and gives a new formula which is similar to the formula of torsion of thin-walled bars. The test and finite element analysis prove that the formula is correct.
