In the design of rock-socketed shafts for supporting axial loading, the end bearing resistance is often ignored, resulting in excessive rock-socket lengths and increased cost. This paper investigates the axial load transfer behavior of rock-socketed shafts based on a database of 99 field test rock-socketed shafts. The shafts are 1.4 to 96.3 m long and have a diameter between 0.5 and 1.5 m. The rock-socket lengths are from 0 to 18.8 meters. The database is developed by collecting information on field test rocksocketed shafts from published papers and reports. The results show that it is important to account for the end bearing resistance in the design of rock-socketed shafts because (1) up to 25% of the shaft head load on average can be transmitted to and supported by the shaft base even at relatively small shaft head displacement in the working range of 5-15 mm, and (2) the portion of the shaft head load transmitted to and supported by the shaft base increases with time due to the effect of creep.
