PLASTIC DEFORMATION CAPACITY OF PRE-ASSEMBLED TYPE BUILT-UP H-SHAPED BEAM BY SUBMERGED ARC WELDING

(Full-scale sub-assemblage tests)

Abstract

This paper investigates on the plastic deformation capacity of built-up H-shaped beam connected with RHS column. A total of sixteen specimens was tested under cyclic loading, with beam size, notch toughness and depth of penetration of submerged arc weld (SAW) as primary test variables. Test results showed that the increase in notch toughness of SAW lead to improvement of plastic deformation capacity, while the decrease in weld penetration did not correlate to decrease in plastic deformation capacity. FEA were also performed to provide insight into the impact of the beam size and the penetration of SAW on the plastic deformation capacity of the specimens.
