Abstract
This paper characterizes the temporal behavior of uplift force generated by turbulent pressure fluctuations in spillway stilling basins. Theoretical a nd experimental analyses are presented that define the magnitude and tempor al evolution of the maximum uplift acting on the lining of such basins. Ana lyses for the dynamic behavior of anchored floor slabs are also investigate d. It is concluded that the applicability of the equivalent thickness crite rion based on the balance of the forces acting on the slabs in static condi tion is unsafe for anchored slabs, because this criterion yields an inadequ ate area for the anchor steel. The results lead to a recommendation to doub le the area of anchor steel as computed by the equivalent thickness criteri on for the design of slabs in stilling basins.
