A solution, based on Ritz energy method, is presented for the uplifting analysis of a uniformly loaded semi-infinite beam supported on a rigid foundation. Motivated by a need to understand the effects of earthquake-induced base uplifting in unanchored liquid-storage tanks, the solution accounts for the nonlinearities associated with large displacements and material yielding in the base plate, and considers the constraining action of the tank wall. The results are in close agreement with those from the exact analysis.
