Abstract

This thesis presents the results of a study that determines the true safety factor of underground square reinforced concrete tank walls.

The walls are analyzed and designed by elastic method. The amount and distribution of the reinforcement was determined by use of the alternate design method (working stress) in compliance with all ACI code requirements. The wall's ultimate moment was computed by use of yield line theory assuming non-isotropic reinforcement. The ultimate value of the earth pressure was computed and compared with the elastic analysis and design values to give the true safety factor.

The results of this study indicate that the safety factor is a function of a number of parameters. Specifically for a square wall the safety factor increases with an increase in the size of the wall. However, the safety factor decreases with an increase in the width of the wall for a given height. For a given width, the safety factor increases with the increase in the height. The rate of change is not in direct proportion to the rate of the change in the size.
