Shear Span

A comprehensive study of the shear characteristics of steel fiber reinforced recycled concrete-filled steel tube (SRCFST) columns is conducted. 50 CFST stub columns are tested with the variables of steel tube diameter-thickness ratio ( D/t), shear span-to-depth ratio (λ), axial compression ratio ( n), and concrete mix. Two types of cements, three recycled aggregate percentages, three water-cement ratios, and three steel fiber contents are considered in design of concrete mixes. The experimental results show that SRCFST columns present the coincident shear behavior of the ordinary CFST columns. As λ is increased, shear resistance shows a downtrend, while the flexural strength presents an increasing trend. Imposing axial compression or thickening steel tube contributes to an adequate safety margin in plastic period. Based on the contributions superposition method, a predicted model of the shear capacity of SRCFST columns is proposed in consideration of shear-span ratio, axial compression, and self-stress.

Measure the temperature change of concrete-filled steel tubular with high strength low heat micro-expansive in its hardening process with different mix proportion. Study self-stress of high strength low-heat micro-expansive and study the relations of the expansive admixtures quantity and its changing regularity with the time. Observe the fail of axial compression short column of concrete-filled steel tubular with high strength expansive under vertical loading, study the changing regularity of its stress under loading.
