Abstract

Filling steel hollow sections (SHS) with concrete can help increase strength and prevent inward buckling, but concrete-filled steel hollow section (CFSHS) using normal concrete has additional dead load. Therefore, lightweight concrete should be used to effectively improve the structural performance of SHS without adding too much load. The addition of rice husk ash (RHA), fibres and
reinforcement bar can increase the compressive strength of foam concrete. This study aims to examine the strength of square hollow sections filled with fibrous modified foamed concrete, which is referred to as reinforced concrete-filled square hollow sections (RCFSHS). A 100 mm x 100 mm x 350 mm short column made of 2 mm and 4 mm-thick SHS was tested under compression to determine the strength of RCFSHS. The modified foam concrete contains steel fibre and polypropylene fibre as reinforcement and RHA as sand replacement. Experimental results show that the strength of the RCFSHS specimen is acceptable and that the addition of reinforcement bars does not significantly affect the strength of compared with unreinforced CFHS.
