By taking the 70 m-span single-layer spherical latticed shell of Kiewitt K8 as the research object,this paper establishes the calculation model by using the ANSYS and carries on stability analysis, from which we can get the stability safety coefficient of latticed shell, calculated length coefficient in different positions and the ultimate bearing capacity considering material nonlinearity and geometrical nonlinearity. Based on the above results, we can provide theoretical basis for engineering structural design.
