ABSTRACT
The Kiewitt-6 single layer latticed shell structure is selected as the research object. The latticed shell’s rapid modeling and global stability analysis are carried out in the form of command flow by using the finite element analysis method. The finite element software ANSYS is used to analyze the Kiewitt-6 single layer latticed shell, and the initial defect of the structure and the material nonlinearity are considered. The load-displacement curves of latticed shells with initial defects and double nonlinearity are analyzed. It is concluded that the stiffness and bearing capacity of latticed shells will be weakened if initial defects and double nonlinearity are taken into account.
