| description | The invention discloses a transmission tower rod member stress calculation method of considering elastic deformation of a tower structure. A finite element method is utilized to establish a finite element mechanics model of the tower structure, and discretization of the overall structure is carried out according to composition of the tower structure; an element stiffness matrix is generated for each element, and the spatial angular relationships and connection relationships between all rod members in the tower structure are combined to generate an overall stiffness matrix by superposition; a load array is generated according to loads on a tower, and a node displacement array is used as an unknown to carry out combination with the overall stiffness matrix and the load array to generate a matrix equation; and node strain is acquired through solving the matrix equation, and stress of each rod member in the tower structure is finally obtained. The method directly carries out precise solving for the transmission t |
