Internal Stability (Stresses)
Learn more about the need to consider uplift pressure when designing a gravity structure at DamFailures.org |
Internal stability failures occur at individual joints, lift surfaces, or other weak planes internal to a dam structure rather than the structure as a whole. This may include sliding on lift surfaces or exceedance of allowable material strengths. [1]
