T The foundation is the lowest structural component of a building that passes the load of the building to the ground or rock that is underneath it. (Hardiyatmo, 2017). The foundation must be able to withstand the load of the buildings above it, without experiencing over-settlement and failure. The methods used in this study are Reese & O'Neill's method for analyzing axial load support and also settlement, and also the Vesic’s method for analysing settlement as comparison. From the axial load test it is known that the maximum drop occurred was of 190.45 mm with a load of 1560 tons. The analytical results of the Reese & O'Neill method calculations on the BH-05A ground obtained a supporting capacity of 1707.8 tons and a working load of 97.6% of 1666.7 tons. In the Reese & O'Neill’s method the settlement occurred was 141 mm while in the Vesic’s method it was 59.3 mm. In the study it was found that the difference between the value of axial support and the actual settlement with the Reese & O’Neill method was 6.84% and 25.96% while with Vesic’s method the difference of settlement occurred was 68.84%. Reese & O'Neill's method is more accurate than Vesic's.Key Words :Axial Load, Settlement, Reese & O’Neill, VesicAnalisis daya dukung aksial tekan dan penurunan fondasi tiang bor menggunakan metode reese & o’nell
