“…e concrete-filled steel tubular (CFST) composite columns are been used in the modern engineering systems. Detailed experimental and computational studies have been carried out in the past [1][2][3]. Main advantages of CFST columns are no reinforced cage and no formwork as the steel tube can extremely be used as formwork and they are fire resistant.…”

Recycling or utilization of industrial waste is becoming more popular as people become more environmentally conscious. Silica fume is a by-product of the smelting process in the silicon and ferrosilicon industries. This study examines the mechanical behavior of steel tubular composite column filled with conventional concrete and silica fume concrete experimentally under axial compressive loading. For the study, variability in steel tube thickness and column height with a constant diameter are considered. To explore the influence of silica fume in concrete, microstructural analyses are carried out by SEM, XRD, and FTIR. The experimental results reveal that the use of silica fume as a replacement of cement is feasible; the silica fume concrete-filled steel tubular (SCFST) column has marginal enhancement strength capacity compared to CFST column as thickness increases.

“…This section presents a comparison between the ultimate load from the experiment and their associated predicted values obtained in different code provisions, which include American Standard (ACI:318 and AISC) (ACI-318, 2011, AISC-360, 2010), European Standard (EC-4) (Eurocode 4, 1994), Canadian Standard S016 (CS) (Karimi and Nematzadeh, 2020), British Standard (BS 5400) (BS 5400, 2005), Chinese Standard (GJB and CECS) (Hatzigeorgiou, 2008; Lu and Zhao, 2010) and Japanese Standard (AIJ) (Morino and Tsuda, 2003) of GBSCFST specimens for both heated and unheated conditions. Some of the code provisions were published in their native language but explained in several research publications that have been followed in the present investigation work.…”

The significant growth of steel production in India has led to a considerable increase in the production of granulated blast furnace slag (GBS). To resolve the environmental concerns associated with GBS production, it can be used as a substitute for natural fine aggregate in concrete within concrete-filled steel tube (CFST). However, literatures regarding the behaviour of GBS aggregate added concrete-filled steel tubular columns (GBSCFST) after exposure to fire is very limited. Hence the present research work aims to investigate fill the aforementioned research gap. A total 30 number of GBSCFST specimens having square, circular and rectangular shapes, including both intermediate and stub columns, are tested. GBS is used as fine aggregate for preparing infill concrete. All the specimens are heated to varying target temperatures of 200°C, 400°C, 600°C and 800°C with a temperature holding time of 2 h in a furnace. Afterwards, the specimens were left inside the furnace for cooling purposes. Axial compression load was applied to all the specimens by using a compression testing machine with a strain-controlled procedure. The reduction in the load carrying capacity ranged from 1.07% to 12.68% for stub specimens and 1.05% to 19.35% for intermediate specimens heated upto 600°C. However, the load carrying capacity experienced a significant reduction reaching a maximum percentage decrease of 24% and 34% when heated at 800°C. The primary failure shapes observed were local buckling and bulging in stub specimens and mid-height buckling in intermediate specimens.

“…The horizontal single chain-dotted lines indicate the elastic limit moment strength, My, estimated based on the AIJ recommendation (AIJ, 2008; Morino and Tsuda, 2003), while the horizontal double chain-dotted lines indicate the full-plastic moment, Mp, estimated based on the superposed strength theory (AIJ, 1987; Morino and Tsuda, 2003). For both calculations, measured properties are used.…”

The long-period ground motions observed in recent subduction-zone earthquake events (e.g., 2011 Tohoku earthquake in Japan) have subjected high-rise buildings to large numbers of lateral cyclic deformations. Concrete-filled steel tube (CFT) columns, which are often utilized in high-rise buildings in Japan, have been studied under lateral demands with a few loading cycles. However, their seismic performance under a larger number of repeated loading cycles is a considerable concern for future seismic events. Moreover, the use of ultra-high-strength steel materials in CFT columns has recently gained popularity. However, studies on CFT columns made using ultra-high-strength steel materials are still limited. In this study, the seismic performance of CFT columns made using conventional steel or ultra-high-strength steel were investigated experimentally under repeated lateral loading cycles. Four cantilever CFT column specimens were tested with a combined constant compressive axial loading and cyclic symmetric lateral loading. Each specimen was tested with two different lateral loading protocols: the conventional protocol with two cycles at each drift amplitude level, and a second protocol with twenty cycles at each amplitude level to represent the lateral drift demand under a long-period ground motion. The effects of the number of loading cycles on the seismic performance of the CFT columns are discussed. Based on the experimental observations, design recommendations are also presented. Moreover, an approach is proposed to estimate the onset of local buckling of the CFT columns under seismic loading.
