Cemented Material Dams (CMDs) have drawn much attention over the last two decades. This study aims to assess the performance levels and capacity of CMDs using Incremental Dynamic Analysis (IDA) with emphasis on the tension failure mode. To this end, Tobetsu dam in Japan was subjected to a set of 17 ground motion records scaled to increasing intensity levels until failure. Then, by considering IDA curves, three limit states were defined for the dam and then, the extent of the damage to its body was quantified through several damage indices. Based on the results, the proposed damage index outperformed available indices in the literature and accordingly, four damage states were defined in line with the proposed index. Finally, fragility curves were derived for Tobetsu dam based on IDA results. The findings revealed that the concentration of stresses in the dam body, especially heel and neck, was insignificant. Moreover, the mean values of the IDA curves in the downstream and upstream directions were in good agreement. Also, the results indicated that the compressive stresses developed in the dam body were much lower than the compressive strength of the material.

在过去的二十年中，胶结材料水坝（CMD）引起了很多关注。这项研究旨在使用增量动态分析（IDA）来评估CMD的性能水平和容量，重点是张力失效模式。为此，日本的Tobetsu大坝受到了17项地面运动记录的记录，这些记录的大小不断增加，直到发生破坏为止。然后，通过考虑IDA曲线，为大坝定义了三个极限状态，然后，通过几个破坏指数对坝体的破坏程度进行了量化。根据结果​​，建议的破坏指数优于文献中的可用指数，因此，根据建议的指数定义了四种破坏状态。最后，根据IDA结果得出了Tobetsu大坝的脆性曲线。研究结果表明，坝体特别是脚跟和颈部的应力集中不明显。此外，IDA曲线在下游和上游方向的平均值非常一致。同样，结果表明在坝体中产生的压应力远低于材料的抗压强度。
