Abstract

Concrete-filled hollow sections (CFHSs) with foam concrete (FC) are a lightweight material used to reduce structural members' deadweight. Research on applying FC filled into steel hollow sections (SHSs) is still ongoing. The ultimate and compressive strengths of FC-filled SHSs are unsatisfactory, and buckling occurs on the tops or bottoms of their specimens. Therefore, this study aimed to improve the strength and reduce the buckling of CFHSs by using FC added with steel fibre (SF) and rice husk ash (RHA). Rectangular SHS columns with the cross-section dimensions of 100 mm × 100 mm × 2000 mm and 2 and 4 mm thicknesses were tested under static load to determine their strength. The cube test was conducted to determine the compressive strength of the modified FC. Results showed that CFHSs filled with RHA- and SF- modified FC had higher strength than CFHSs filled with RHA-modified FC. Therefore, using modified FC as concrete material in CFHSs is acceptable.
