【Abstract】 The preprocessing and postprocessing modules programmed by Visual Basic,structure the main body frame of the sofeware;we use object oriented programming(OOP) to programme friendly Windows user interface,and use model data base to manage and modify the tower model data;The calculating modules programmed by Digital Fortran can carry out geometric nonlinear finite element analysis,It overcomed the shortcomings of calculation with linear FEM in traditional design, and the result can satisfy the needs of the design of steel tube poles;and we can use the platform of AutoCAD to show tower drawing and visual modeling.更多还原
