Background and Objective: Trapezoidal Cemented Sand and Gravel Dam(trapezoidal CSG dams) are new type of dams which recently considered as environmental point of view specially. These types of dams have less negative effect on environment specially compare to concrete weight dams. Considering the positive environmental performance of these dams, it’s important to assess their structural performance. Method: As the dynamic researches on CSG dams are so limited, this research will analysis the trapezoidal CSG dams using finite element method with ABAQUS software. Findings: To calculate earthquake damages, fragility curves plotted based on damage index which is the length of cracks on the dam base and areas of the cracks on dam. Discussion and Conclusion: The final results of this research shows trapezoidal CSG dams comparing with concrete dams showing a good structure resistance and in some other sampels they showed a better performance than concrete gravity dams, considering the materials in trapezoidal CSG dams weakened to reduce the negative environment aspect of dams.
