Paper Title:
Stiffness Analysis of Welded Spherical Joints with Rib Stiffeners
  Abstract

Joint’s stiffness has important influence on stability bearing capacity of large-span spatial reticulated shell. The welded hollow spherical joint with rib stiffeners is a type of joint applied widely on large-span spatial reticulated shell. In this paper, the axial flexibility and flexural stiffness of welded hollow spherical joint with different rib stiffeners are analyzed with the FEM software ANSYS, compared with the non-rib hollow spherical joint’s stiffness, then the calculation formulas of the axial flexibility and flexural stiffness under different rib stiffeners are given through regression analysis. Some important conclusions were obtained, which can provide theoretical foundation for the stability bearing capacity analysis considering joint’s stiffness and can be applied on practical design..
