| description | This report presents an experimental investigation on the structural behaviour of square recycled
aggregate concrete filled-stainless steel tube (RACFSST) stub columns under combined
compression and bending. A total of twelve square RACFSST stub column specimens fabricated
from two stainless steel square hollow section (SHS) tubes and three types of concrete with
recycled aggregate replacement ratios of 0%, 35%, 70% were adopted in the tests. Material tests
were also conducted to obtain the material properties of recycled aggregate concretes and
stainless-steel tubes. The combined loading test setup, procedures, and observations, including
the load–mid-height lateral deflection curves, failure loads and failure modes, were fully reported.
The effects of cross-section size and recycled aggregate replacement ratio on the load-carrying
capacities of RACFSST stub column specimens were examined, followed by the discussion on
the development and distribution of strains. Three current design codes were used to assess the
square RACFSST stub columns under combined compression and bending. The result concluded
that the European code and Australian standard have demonstrated great level of consistency and
accuracy of failure load prediction accuracy while American specification demonstrated
conservative failure load predictions with high degree of scattered points. The European code
displayed the most accurate failure load predictions among the three design codes. |
