Tests on impact behaviour of micro-concrete-filled steel tubes at elevated temperatures up to 400°C

Dynamic compressive behaviour of concrete after exposure to elevated temperatures

“…Huo et al [10][11][12] conducted a series of experiments on impact behaviour of concrete materials (including normal concrete and concretefilled steel tubes) at and after elevated temperatures, from which a lot of beneficial conclusions can be obtained. Literatures [13][14][15][16] also investigated the dynamic properties of the heated concrete from various aspects.…”

Behavior of concrete filled steel tubular (CFST) members under lateral impact: Experiment and FEA model

“…Bambach (2011) [7] and Bambach et al (2008) [8] investigated the performance of square CFST members subjected to lateral impacts at the beam mid-span and a design procedure was also developed. Impact resistances of small-size micro-concrete-filled steel tubes under axial impact loads at elevated temperatures up to 400°C were experimentally studied by Huo et al (2009) [9].…”

Experimental and numerical investigations of the compressive behavior of concrete filled steel tubes (CFSTs)

“…It was noted that the dynamic impact factor (DIF) of CFST specimens was smaller than that of a plain concrete specimen under the same strain rate impact. Huo et al [10] axially impacted small sized micro concrete-filled steel tubes at elevated temperatures up to 400°C. Minor load capacity increase was observed for the specimens at ambient temperature after the steel tube yielded, though the specimens at elevated temperatures displayed notable increase in load-carrying capacity.…”
