Optimal Lower Bound

A generalized procedure based on finite elements and nonlinear programming has been presented in this paper for finding the optimal lower bound pull-out capacity of inclined strip anchors in sands. The results obtained are compared with the values reported in the literature to validate the suggested method of analysis. The predicted values are found to be in excellent agreement with that of Meyerhof. Key words : limit analysis, lower bound, nonlinear programming, inclined anchors, uplift capacity.
