Paper Title:
Experimental and Finite Element Analysis on the Ultimate Bearing Capacity of Hollow Spherical Joints with Ribbed Stiffener
  Abstract

Four groups (12 in total) of welded hollow spherical joints with ribbed stiffener were tested under uniaxial loads in this paper. With the adoption of elasto-plastic model and consideration of geometric and material nonlinearity, the whole loading process of the specimens was simulated by ABAQUS. Through combining the test data and computing results, two recommendations used to quantitatively determine the ultimate failure load of spherical joint in test are proposed. The relationships between bearing capacity and various influence factors, which include the thickness and diameter of hollow sphere, diameter of steel tube are analyzed and illustrated at the end of this paper.
