“…Experimental research on a shaking table of two different curvature arch dams was undertaken in this work to identify the deterioration process in arch dams after a major earthquake. The majority of dynamic arch dam experiments concentrated on a specific element, such as the impact of contraction joints opening [8,17] or dam-reservoir correlation [9]. The findings were compared to those of the numerical research.…”

Seismic responses of cracked scaled-down arch dams were investigated by experiment on a shaking table. Two different curvature models (M1 and M2) were cast by using a plan concrete. Dams properties, including materials and dimensions, were carefully simulated. A significant earthquake magnitude with (7.7M) and water pressure were applied on the dam's models. Considering water and seismic loadings, the dynamic reactions of the arch dam's system were investigated. Both models showed crack overstresses or propagation on the dam's model as a result of seismic excitations. The arch dam with a higher degree of curvature was recorded 44 Mpa of stress evaluation which less by 30.7% of the arch dam with the lowest degree of curvature. The results indicated that raising the degree of curvature led to raising the dam's stability, earthquake resistance, less displacement, and less growth of tensile cracks.
