Finite Element Analysis on Joint of Ultra-High Steel Columns and Steel Core Barrel Outrigger Truss
The elastic and plastic characteristics of the Y-joint of frame-core tube structures with steel pipe column and steel pipe outrigger truss is studied in this paper. The finite-element method is adopted in the numerical study. To avoid the damage of the joint, controlling the relatively convex-concave deformation of the column wall through adding internal stiffener plate is discussed. Through the comparison of numerical study of the Y-joint with different shape of stiffener plate, a feasible design of the Y-joint is given.
