Elephant foot buckling
WebNov 16, 2016 · This is known as elephant's foot buckling failure because of its characteristics shape. This failure can cause serious damage to the tank and silo under … WebThe robust concrete wall of the primary containment tank can take out-of-plane bending loads and is not susceptible to buckling, such as elephant-foot buckling, that steel inner tanks face. Once the wall panels are fully integrated by wire wrapping, the concrete wall can sustain the full wind load without bracing. ...
