| Abstract | ||
| The ultimate bearing capacity of ring footings for different conditions such as internal to external diameter ratio and angle of internal friction for sand is determined using the finite element program ELPLA Professional Edition, Version 9.0. A semi-empirical relation for determining the bearing capacity of ring footings that developed by other researchers is also described and used in compared. The value of ultimate bearing capacity is found to decrease significantly with an increase in (r =di/de), where di and de are the internal and external diameter of the ring, respectively. For larger values of internal friction angle of soil (), the magnitude of ultimate bearing capacity is seen to be higher than smaller values. The obtained results are compared with those available in the literature. | ||
