【 摘 要 】

Steel-reinforced concrete (SRC) columns have been widely used over the past few decades. This paper presents the results of an experimental study on short SRC columns under sustained axial loading. Long-term axial deformations due to shrinkage and creep of the concrete were recorded. The ultimate strengths of the columns after long-term loading were also determined, and the results showed that the sustained axial loads had no significant effect on the axial compressive strength of the SRC columns.
