Structural Performance of H-Beam-and-RHS Column Space Subassemblages Reinforced by Increasing Column Thickness

Abstract

The structural performance of H-beam-and-RHS-column space subassemblages subjected to the cyclic reversal loading under high compressive force on the column are presented. The column thickness at beam-to-column connection area is increased by the induction heating process. The structural performance and failure mode of the specimens were investigated by the cyclic reversal loading test . The finite element and in-plane numerical analyses are carried out to estimate the elastic-plastic behavior of the specimens. The local strength of beam-to-column connection subjected to bi-axial bending moment is evaluated by the yield line theory.
