Ultimate Capacity of the K-Type Overlapped Rectangular Hollow Section Joints

Abstract:

The intensity calculating of simple joints is one of the most important thing in the design of space truss with hollow sections. By using the finite element method and close reference to material and geometrical nonlinear properties, numerical simulation analysis of the ultimate strength of K-type overlapped Rectangular Hollow Section joints under the axial force and bending moment was studied. The influence of the overlapped ratios and other geometrical parameters on the ultimate bearing capacity was investigated and explained graphically. With the thickness ratio of the chord bar and web member increasing, the ultimate capacity increased. And with the overlapped ratio increasing, the node capacity reduced.
