Abstract
![CDATA[This paper investigates the section capacity of a series of concrete filled fabricated VHS tubeplate triangular sections under axial compression. The behavior of empty fabricated sections made up of mild steel plates with tubes at the corners was investigated in previous studies which have proven the effectiveness of the use of the empty fabricated VHS-plate section columns. In this paper concrete-filled fabricated triangular columns made up of VHS tubes at the vertices that are welded to mild steel plates are tested. Concrete-filling results in reduction in cross sections of the columns thereby reducing construction costs and contributing to sustainability. The VHS tubes used in this investigation have a nominal yield stress of 1350MPa, nominal ultimate strength of 1500MPa, 38.1mm outer diameter and 1.6 wall thicknesses. Steel plates of grade 250 with a 3mm wall thickness were used as facet plates. Experimental tests were conducted to determine the loaddeformation curves and understand the behavior of the concrete filled VHS fabricated triangular sections. In addition, the paper assesses four international specifications used to design concrete filled steel columns, and compares their prediction to experimental results.The specimens'carrying capacitieswere also determined using the Australian standards taking into account the effective section area.]]
