Experimental study of laser-welded stainless steel angle columns

Structural response to axial testing of cold-formed stainless steel angle columns

“…The presented results are a part of an on-going comprehensive investigation addressing cold-formed, hotrolled and laser-welded stainless steel equal-leg angle columns with pin-ended boundary conditions, conducted at the University of Belgrade, Faculty of Civil Engineering [15], [16]. The investigation includes experiments and geometric and material nonlinear finite element failure analyses, proposing design procedures that take into account the cross-section slenderness, material non-linearity and initial structural imperfections caused by different production processes.…”

Design procedures for cold-formed stainless steel equal-leg angle columns

“…Clauses 2.2 and 2.3 of the Australian specification AS/NZS 4673 [21] (based on the American standard SEI/ASCE-8 [26]) adopt provisions from the AISI Specification for cold-formed carbon steel [27] for determining the effective width factor for uniformly compressed stiffened and unstiffened elements (Winter's plate buckling curves), using following equation: (9) where λ is the slenderness ratio of the plate element and can be obtained through:…”

“…Although significant experimental work on beam and column strength of coldformed stainless steel hollow sections has been carried out, research on stainless steel open cross-section members has been less studied. Most research on non-doubly symmetric stainless steel columns has been concerned with local, distortional, flexural-torsional and flexural buckling behaviour with respect to lipped channel sections [1], plain channels sections [4], [5] and equal-leg angle sections [6], [7], [8], [9].…”

Major‐axis buckling of pin‐ended stainless steel equal‐leg angle section members: FE modelling and design

“…Stainless steel equal-leg angle section columns with pinended support conditions have been studied in a number of previous investigations [4,[6][7][8][9][10][11][12][13][14], where they are focused on angle section columns pinned about the minor axis, the findings of which are described in [4]. To the best knowledge of the authors, there has been no experimental investigation reported on stainless steel equal-leg angle section members cylindrically pinned about the major axis, and subjected to compression or combined compression and bending.…”
