| 摘 要： | 本文叙述了按空间受力状态,采用矩阵位移法对桅杆结构进行精确的非线性分析问题。文中给出的计算公式可适用于一般情况下平地与山地桅杆的静力、温度应力、支座沉降、自振特性和抗地震计算。本文的结构分析考虑了桅杆杆身的轴向变形,纠正了计算桅杆温度应力所沿用的不确切的分析方法。文中的理论分析得到了模型试验的验证。首都323米大气污染监测塔的结构计算,采用了本文的计算方法及其计算机通用程序。

| Abstract: | This paper discusses a rigorous nonlinear analysis of guyed masts by the matrix displacement method considering its spatial behavior. The formulas presented can be used in the calculation of statical forces, thermal stresses,settlement of supports, dynamic characteristics and aseis-mic analysis for guyed masts located in plain or hill lands under general conditions. The structural analysis considers the axial deformation of the tower mast and corrects the inexact method used in the current calculation of thermal stresses. The theory presented was testified by a model study. The calculating method and its general computer program were used in the structural analysis of a 323 meter atmospheric pollution monitoring tower in Beijing. |
