In this article, we present an analysis of the axial compression behavior of thin circular tube columns filled with concrete. Experimental study was conducted by using one concrete composition and two lengths of columns. Thirteen columns were tested in axial compression. A comparison of experimental results with Algerian design codes DTR-DC, AIJ, DL/T and the empirical equations from the literature was performed. The analysis results for the thin tube show that the axial capacity in compression is underestimated by the DTR-DC. However, DL/T and AIJ codes are in agreement with test results. The results of empirical equations give different results depending on the length columns and section type.
