斜拉结构桅杆计算方法研究

斜拉结构的桅杆受到斜拉索和屋盖结构的力使得上端倾斜过大,出现大位移的几何非线性特征,所以须找出模拟桅杆单元的矩阵位移法来进行有限元计算;同时,需要通过倾覆稳定和压屈稳定来分析与其刚度相关的整体稳定性。

Research on Calculation Method of Mast of Cable Stay Structure

Because the top of the mast tilt is too large,there is a large displacement of the geometric problem of nonlinear characteristics,so it needs to find the matrix displacement method which used to simulate the mast cell to carry out finite element.At the same time,we need to analyze the overall stability of the structure,which is associated with the mast stiffness,through the overturning stability and buckling stability.
