STIFFNESS ANALYSIS OF WELDED SPHERICAL JOINTS WITH RIB STIFFENERS
Joints stiffness has important influence on stability bearing capacity of large-span reticulated shell. The welded spherical joint with rib stiffeners is a type of joint applied widely on large-span reticulated shell. The axial flexibility and flexural stiffness of welded spherical joint with different types of rib stiffeners are analyzed with the software ANSYS,compared with the non-rib welded spherical joints stiffness,then the calculation formulas of the axial flexibility and flexural stiffness under different types of rib stiffeners are given through regression analysis in the paper. Some important conclusions were obtained,which can provide theoretical foundation for the stability analysis considering joints stiffness and can be applied on practical projects.
