Abstract：A fragility analysis methodology based on least squares support vector machine was presented. Using the results of finite element analysis as learning samples, the least squares support vector machine could be established, and integrating the learned model with Monte Carlo simulation, the fragility curve could be obtained with high accuracy and efficiency. Using the proposed methodology, the anti-sliding stability fragility of non-overflow section of a concrete dam was analyzed and the sensitivity of the key parameter was studied. The results show that the dam could ensure the dynamic stability under design earthquake and possess high margin in safety.
